08:05:23 Okay. 08:05:20 Welcome to the fundamentals of gaseous halos KITP workshop, when we were first planning and four months thereafter. I was imagining today, I'd be looking at of use something like this. 08:05:32 When I look out my window here. It's snowy and we're in the middle of winter in Michigan. 08:05:38 We realized a few months ago that we're just going to have to deal with a remote workshop. And in a way, it's scary. Exciting. 08:05:51 I see that there are already 123 participants. And there's no way we do had you all a KITP if this workshop would have been in person. So the fact that it has to be remote actually opens up a lot of possibilities and has forced the organizers to be very 08:06:09 creative. 08:06:11 And I'm just laughing to myself because in a strange twist of scheduling I can hear the W yes meeting coming from the other room. 08:06:19 But we're having KITP over here. 08:06:23 This meeting would not have been possible without all the organizing team. And I want to thank Cameron Hummels and Ben Oppenheimer and just work, who I don't know maybe you can say hi maybe can can like unmute yourself and say hi. 08:06:39 Briefly, we've been putting our heads together. 08:06:41 If you want to say hi going go ahead now. Hi. Hello. 08:06:48 Later, 08:06:51 and we've been doing our best to try to come up with a meeting that can be inclusive. 08:06:58 That can be organized. 08:07:00 That can have things opportunities for experts to talk to experts and also people to learn more about what their colleagues and other sub fields are doing at any point in the meeting if you want to contact us about anything that's happening, we've set 08:07:18 up a Gmail, email address, that just goes to the four organizers. 08:07:24 So if you want to communicate directly with us. There's the email address down here at the bottom of the screen kitp.halo21@gmail. com. 08:07:33 Okay. 08:07:34 And in trying to figure out how to organize the vast topic now of fundamentals of galactic halos or, sorry gaseous halos. 08:07:44 We settled on this set of eight broad questions. 08:07:49 There's eight weeks, we tried to figure out how to capture the breadth of the subject in eight questions one per week where you don't have to work on this question that week, but it will be the motivating question of the discussion. 08:08:07 Here I thought I heard somebody say something. 08:08:10 So, here the questions are. And please, volunteer to help us in any way you can. 08:08:19 Because the way we've set things up. 08:08:22 We're counting on the community to do a lot of contributing. 08:08:27 And I hope that everybody who's on this call right now can see at least one question maybe more where they already know something they can contribute to the meeting. 08:08:39 The up the elements. You can read about them in more detail in the organizational document we mailed around, but I just want to briefly talk about our intentions for each of these elements. 08:08:56 The first one, each week is going to have to keynote talks. 08:09:02 And we have asked those speakers, to give broad perspectives to consider the question we posed for the week, and try to orient everybody in the meeting to what people are now thinking what has happened, what they anticipate happening in regard to that 08:09:19 question. 08:09:20 So, we're still in the process of scheduling all that. But we have keynote talks now scheduled for the first few weeks of the meeting. 08:09:29 The next thing we're going to have is tutorials. So the idea here is on Wednesdays. We're going to have a quarter presentation where we've asked people to help others understand some topic that relates to their research. 08:09:50 And so the idea here is, we have a broad variety of people who are involved in the workshop. And we want everybody to become a little more familiar with what each other is doing. 08:10:01 And so, that's the part of the tutorials and we are looking for volunteers. So if you want to give a 20 minute tutorial, followed by question and answer. 08:10:11 Please project the organizers with your idea, and we'll try to find a slot for you right now. There are a lot of open slots. So those will also be recorded and made available for later viewing. 08:10:24 So, in a way, you can think of it as a little bit legacy project, unless you make the tutorial, there might be a number of people who learn from it, not just that week but into the future. 08:10:37 Next thing is one of the features of a usual KITP meeting is the opportunity to talk with a bunch of world experts who just happened to be on that hallway. 08:10:48 We can't do that in person, but we can try to do that through slack. And so, we are inviting people to propose conversation groups, where you will, will set it up on slack and people who are in that sub field can discuss things there. 08:11:04 We also are hoping that they will be linking to and discussing topics that have come up in the tutorials the keynote talks. 08:11:13 Anybody can join a conversation group, but we want them to be led by people who are really expert in that subfield 08:11:22 on Friday. What we're hoping is that at very least, the people involved in conversation groups, during the week where that question, most pertains that conversation group will be able to bring back to a larger group, what's been happening with the Halo 08:11:41 discussion has been what ideas have come up and we is going to be fairly. 08:11:49 We don't know exactly how it's going to work yet how to organize the broad group will probably be identifying topics and having people break out into breakout rooms and come back and talk. 08:11:59 But that's what's gonna be happening on Fridays. 08:12:05 Um, something I guess I am particularly excited about is the idea of how do we get contributions about new results. And so we are setting up a format where anybody who's participating can contribute a four minute video about some new result that they 08:12:22 have that they'd like to share. 08:12:25 And we want to organize that on YouTube, in a curated site on YouTube, where we will collect contributions. And once there their conversation groups can link to them. 08:12:37 And we can substantiate what you're talking about, or learn what others are doing through that series of videos so I also hope to get you thinking about what you might want to share with your colleagues in a, in a brief video that will post. 08:12:54 And then something you will get the opportunity to do later today is a speed collaboration, Jess Werk will host that today, where we're going to give you the opportunity to be in a room with a series of colleagues one on one for a few minutes to brainstorm 08:13:12 ideas, and still I'll have just talk more about that, but before it happens. A little later today. 08:13:20 I also anticipate, we're not going to go the full two hours allotted today because normally we would be having more to talk about near of conversation groups, but right now we're just getting started. 08:13:34 Now, I want to pause, just to see if anyone in the group has some questions about these program elements that we can answer for the group 08:13:48 can raise your hand if you, if you have a question about these elements. 08:13:54 Raise your hand if you, if you have a question about these elements. Okay, I see one from Natasha, Natasha. 08:13:59 Yeah. 08:14:01 So I was wondering for the group for sort of conversation groups are these meant to be really more specialist and even looking at few of the things that are up there now and content yeah well let that all looks actually looks quite interesting actually 08:14:14 so how specialized are these things, supposed to be. I would say this. 08:14:20 Anybody can join if they want to learn what's going on, I think, in the, in the, kind of, we have keynote talks and tutorials where we're asking people to speak to a broader audience in a conversation group that will go how it goes. 08:14:36 Right. 08:14:38 So, not demanding that everybody provide complete background everything they say, if you want to listen and learn. That's really great. We encourage that. 08:14:46 But that's the place where if you really want to roll up your sleeves with colleagues and dig deep. That's where we expect that to happen is that clear. 08:14:54 Okay, thanks. 08:14:57 Any other questions before we move on. 08:15:03 Okay, I see a question. Oh, hello. 08:15:10 Yeah, go ahead. Marcus. 08:15:14 Hey, good. Yeah, so how can we propose tutorials and or any of the other format. So we just took the organizers will try to get set up. Yep. 08:15:27 So yeah, you can look over the weeks. 08:15:35 As they said right right now things are pretty wide open. 08:15:35 And you will see that the tutorials and this week are kind of heavy on the organizers because we're trying to demonstrate everybody else like what's happening. 08:15:44 But yes, we welcome tutorial ideas. 08:15:53 Question those results videos are they going to be spread out of all these eight weeks, would say yeah we want it. 08:16:02 If you have a new result that's relevant that for the week question eight weeks from now put it up now, right, as long as you have it, make that video available. 08:16:10 So we want me to do is if you have a title, a two or three seconds, little abstract like a mini abstract just so people know what it's about. 08:16:19 We want to kind of curate them as much as we can so people can find new results and just look at them, obviously in four minutes, you're not going to be able to dig very deep but it's a way to make people aware. 08:16:32 So we, anybody can submit one at a time. And we'll just stick them up. 08:16:37 Okay. Can I Can I just add really quickly, um, Mark you you threw up the email for the organizers, which is a fine way to get in touch with the four of us. 08:16:49 However, we're all on Slack and those of you familiar with Slack can dm us, you can start your own channel, which might indicate that you're interested in a specific topic. 08:17:01 So, um, you know, If you're familiar with Slack, Slack is a great way to get in touch with the organizers and with anybody else involved in the workshop. 08:17:16 Any other questions at this time. 08:17:18 It's also worth noting that for people interested in submitting a new results video, we're primarily going to do that over the Slack channel. Halo 21 dash new results. 08:17:29 So you can produce your, your video locally, where you're talking to the camera or sharing your screen showing your paper or your result or whatnot. And then once you've completed it and made it to a popular video format like MPEG or quick time or something 08:17:47 like that, feel free to upload it into the Slack channel Halo 21 new results and we will post it to the YouTube channel, and then share that later in the, in the meeting. 08:17:58 Yes, I guess. When I think of it sometimes I think we're going to have an eight week long poster session. 08:18:04 So yeah, if you miss a poster it's still there right. 08:18:11 Any other questions at this time. 08:18:14 There's a question in the chat. 08:18:16 Okay, I, and it is let me see. Oh, how does the acknowledgement process, we'll proceed with a specific topic program during writing a paper and feature and collect benefits. 08:18:27 Okay. 08:18:29 Um, yeah, KITP in the past has said if you have been to KITP and worked on a paper. While you're there, or had some ideas where you're there, there's an acknowledgement that should go in your acknowledgement section, and they have a specific forum for 08:18:47 doing that. Um, 08:18:50 I guess I'm sure they would love us to do that, if you have benefited from this workshop, while doing your work. Obviously we're not residents. 08:19:02 But if you like KITP as an institution, you help them by acknowledging them in your fingers. So they're grant funded partly by the NSF. And so, when they write their proposals the number of citations are, you know, I shouldn't say citations number acknowledgments 08:19:21 they get matters. Okay. So I think if we had Lars Bildsten here today, he'd been encouraging you if the meeting has benefited URL helped your work, please acknowledge the KITP and they have. 08:19:36 I don't we don't have it in our program description document, and maybe we'll put it up. 08:19:43 Well ask Lars what kind of acknowledgment they would like to see, and we'll put it in there. 08:19:48 Okay. 08:19:50 Any other questions. 08:19:54 Okay. Oh, Sanyutka 08:20:06 to us for the tutorials do we need to have some specific, like specific knowledge in that some deeper like a level you have. 08:20:22 Besides on like 08:20:23 my, the audio for me is a little fuzzy so I haven't made it out I think you're saying that the tutorials, you're asking what kind of acknowledgments are necessary in them. 08:20:37 I'm asking, what level of proficiency in law. 08:20:41 You're giving a tutorial like 20 minutes to what level of expertise is required. 08:20:47 I would say. 08:20:51 I think the tutorials are going to be a wide range of things in fact, one of our motives inside the first week, is to show the diversity of what we have in mind that I will be doing one on Wednesday. 08:21:07 That's about the seemingly simple concept of variable temperature that I hope will be suitable for a first year graduate student even undergraduate. Cameron will be talking about a specific piece of software tried, which is used to analyze simulations 08:21:20 of the CGM and Prochaska will be talking about the subject of FRBs and how you probe the CGM with them. 08:21:32 And so, that should span a large variety of things, and a different number of expert levels also. But the idea is not to speak only to the experts, it's to open a door for your colleagues to learn more about what you do in your sub field. 08:21:49 Okay. 08:21:53 But I think, expect a variety in the tutorials 08:21:58 Is that clear. 08:22:10 Oh, Yeah. 08:22:04 Okay. 08:22:05 Any other questions. 08:22:11 Ah, er Yes, Evan Scannapieco is posting the chat being expert in the, the, what grant agencies like to see. 08:22:23 He has put an acknowledgement suggestion right there in the chat. 08:22:28 I don't know about that but that's the grant number so. Okay. 08:22:32 Based on what is done the past Yeah, thank you. 08:22:36 Ah, alright. 08:22:39 So, again, I hope, really, we're all going to be learning more as we try this out by example how these program elements work. 08:22:49 The, the organizers have benefited partly from some of KITPS prior experience, but they have let us know that, I think so far we're the most ambitious. 08:23:05 In embracing the possibilities of digital media. 08:23:05 So we'll see how it goes and I hope you all enjoy the adventure and learn along with us. 08:23:11 I want to step on now. Usually what will happen at this time is a more extensive introduction to the question of the week then I'm going to give here. 08:23:23 The first question is how do gaseous halos depend on Halo mass, and we chose it because it's, you know, it should be all encompassing 08:23:35 regarding what we're talking about in this meeting, we want to be talking about everything from a CGM around dwarf galaxies to the inner cluster medium around galaxy clusters and try to see what kind of physics underlies it all. 08:23:49 And so, we're starting with this question. 08:23:52 And so you can see the keynote speakers that we have for the first week. 08:23:59 I have already mentioned the tutorials that we have planned and the new conversations, they're all new as of this week, but the ones we already have initiated are the XCGM conversation, and the FRBs conversation and dot dot dot means anything you'd like 08:24:19 like to start this week just let us know. It doesn't have to even pertain to this question, we want conversations to get started. And when the week, or weeks come when your conversation is relevant. 08:24:34 We may have you be a featured conversation and speak to the entire group about what's been happening in your slack conversation. 08:24:43 So, at this point, I want to turn it over to Ben, to talk about the XCGM conversation, and what we hope to discuss there, you ready. 08:24:54 Yes, I am. 08:24:55 Thank you Mark for a great introduction. 08:25:00 And I assume, unless I hear feedback people can hear me all right. 08:25:06 Um, yeah so these are, these conversation groups are a great idea and I am going to share my screen, and 08:25:20 go into presentation mode. 08:25:24 And I just put some slides together with Mark hasn't driven to these yet he's been very busy preparing the introduction. 08:25:33 So, he will be a part of this one of the initiators here and the focus here is the the hot side of the CGM, and I know I'm quite interested in the, you know, ultraviolet absorption mind side of the CGM given you know previous work I've done, but I've 08:25:50 gotten into the X ray CGM, and that the hot CGM is not just x rays, it can be FRBs it can be Snyder's Zelda pitch. 08:26:00 But I think we should have a continuing conversation that that spans 08:26:05 Maybe the whole, whole 08:26:10 program, all eight weeks and it will be featured more prominently some weeks than others. And I think the first two weeks are very pertinent for this conversation. 08:26:23 You know, I, you know, usually we would have 15 minutes for presenting this week's you know one of this week's conversations. I don't think I'm going to go that long today. 08:26:34 But I did want to go over sort of some of the logistics. 08:26:40 And the main place to go is the Slack channel, which is Halo 21 x CGM, and I last time I checked, I saw already self 50 people on it and it's definitely open and people should feel welcomed and not intimidated of about joining. 08:27:01 And I think what we will do is, we're kind of an online Google document I've already had somebody work on this a little bit, and it'll be a living document, which we are all invited, there's, I wrote these sites very fast so there's a lot of spelling 08:27:19 errors. 08:27:21 To edit and expand and something that I really want to take an opportunity to do is have in person interaction. 08:27:32 Outside normal Halo 21 hours. 08:27:37 And, and come up with some targeted interaction, often pertaining to the weekly keynote talks, and also maybe like allow live participation at a time that is outside the usual eight to 10 pacific time, presentations, especially for some of the people 08:27:57 we couldn't accommodate as easily such as people in Australia and East Asia, and maybe Israel as well. 08:28:07 So, you know, some of these first couple weeks I'm happy to set up a couple times to meet. And I already put a doodle up there, and so feel free to put in those gauge interest as well. 08:28:22 And on Friday we will present some of the results of our conversation. 08:28:28 And so I'm excited about making some progress. 08:28:30 A little bit, you know about why study the, well, I should say x ray CGM, or just hot CGM. 08:28:40 And, you know, one thing that we will talk a lot about is the cool you ultraviolet phase, but that lives in a medium. That is likely tenuous diffuse hot and understanding that phase and the invite you know the the medium in which the cool phase lives 08:29:01 and forms out of it interacts is crucial as of as part of this program. 08:29:07 And I think we will hear a number to a lot about how does cool gas cool or precipitate out of a halo, and on what timescale. 08:29:17 Number three, something that is especially pertinent for this week is how does Halo mass, you know, how does the hot phase change as a function of Halo mass and is there a certain Halo where you transition from primarily cool phase two hot phase. 08:29:37 And we all know probably or most of you, a lot of us have talked in this field have talked about missing baryons. And where are they are they are they in a hot phase, are they ejected from the Halo, or are they a combination of both. 08:29:53 And I, something that I'm really interested in is just a hot Halo medium around like a milky way galaxy originate from galactic processes like feedback, heating or is it a hero process, such as visualization. 08:30:10 You know, I think the, you know, on the X ray side of things, the motivation is driven by a lot of observational observational momentum. And there's, especially some, you know, some recent CGM data from in over the last several years that I don't think 08:30:29 has been completely digested by the CGM community, especially from xmm Newton of nearby galaxies. 08:30:39 Number two, eRosita is launching success successful and it's, I believe, capturing, you know, the most X ray photons ever. I can't confirm that I think that's right. 08:30:49 And it will allow a revolution revolution a new approach to that X ray CGM. 08:30:56 And, you know, there's missions that bridge the gaps, you know, between massive clusters. The ICM two groups the group medium to the CGM which is, you know, more like Milky Way mass galaxies or individual galaxies dominating their halos we'll also talk 08:31:14 about extra absorption spectroscopy which is sort of, you know, a little bit of a desperate field right now you have only a handful of absorbers and they're talked a lot about but I think that will change. 08:31:26 Hopefully with a mission to be launched in the 2020 Arcus, or, or something similar to that. And, of course, on the horizon with some with question marks next to them, are a number of missions. 08:31:40 I mean it doesn't have you know if the nuc will be launched XRISM is going to be launched next year, and longer timeline and based on the Cato are things like links and access. 08:31:50 I missed a couple there. 08:31:52 And something I want to emphasize is that we are not just limited to the this the CGM to a halo master is like hosting. 08:32:03 You know, dominant central galaxies, like the Milky Way. 08:32:08 We'll be talking about the entire group medium. 08:32:12 The Intra-cluster medium in a holistic sense, and also I mean, it's kind of funny actually astronomers call IGM. The Inter- group medium, but we will use these terms, the IG little RM throughout the, the discussion here just to make it clear to everyone. 08:32:31 There's going to be a lot of discussion topics are ongoing. And that's kind of covered in some of the main questions and this is incomplete we'll fill this in as we go through the program, and I don't know, um, you know, I encourage you to fill out the 08:32:48 doodle I do want to meet maybe as soon as tomorrow. I definitely have something that, you know, something basic, I can, you know, I can talk about is, you know, just talking about extra observational units and trying to approach them a from a theoretical 08:33:08 sense and something that I've run into is. 08:33:11 It's hard to look at some of these recent results, especially of, you know, the X ray emission around normal like spiral like galaxies and electro galaxies is often there are units in these papers that are very different during counts per second or accounts 08:33:32 for a given telescope for a given instruments and something that I, you know, want to take the opportunity here to to advocate for us to come up with like a standard set of of units that observers and theorists and simulators can all work on and such 08:33:55 as, you know, so you know some units of for surface brightness. 08:34:00 For a source X ray spectrum. So that's sort of some of the things that we can start talking about this week, and I think I will stop my share now and take any questions. 08:34:15 And hopefully, generate some interest. Thank you. 08:34:30 Thanks for the hand, Mark. 08:34:34 Yeah. 08:34:35 Okay, um, now we have another group that is starting conversation group, the fast radio burst group. I not formally an initiator. If any of the initiators are here. 08:34:51 I'll give them a moment to step up. I know that least one of them couldn't make it. 08:34:57 If no one. 08:35:05 I think he declared that I'm an initiator so excellent go ahead Brian. 08:35:06 Um, I don't have any sort of bespoke slides but I can just give a quick overview, with a couple of slides from other talks if that's if that's useful. 08:35:24 Okay, so fast, fast radio bursts are just the most wonderful thing that one of the most exciting things in astronomy right now I think I'm sorry I should introduce myself. 08:35:34 I'm Brian Gaensler live from the University of Toronto. So, they're very sudden, as the name suggests, they have a sudden brief millisecond very bright flashes of radio emission that occur randomly throughout the sky, perhaps with around 1000 of them, a 08:35:54 day. They are now known to be coming from distant objects, we have about 14 of them that have been localized to distant galaxies at low redshift, but the exciting thing for for this conversation is that they're polarized, and that means that you can detect 08:36:17 the rotation measure of these bursts which was the integral, on the entire line of sight of n video. And they're also because they're impulsive they're also dispersed, which means that you, you get a measurement of the total electron column on the line 08:36:29 of sight, as well. 08:36:31 And so you get two numbers, there's actually more information you get you get scattering as well. 08:36:37 But you can combine those two just dividing RM by the DM, and then you get a direct estimate of the average line of sight, magnetic field one one side. 08:36:46 So here's a scenario. This is from one of the press images from exes results. 08:36:53 You have fast radios and some different galaxy and you detect the earth, and you have this giant integral along the entire sideline, and you have all of these different components that contribute to the rotation measure and the dispersion measure. 08:37:08 And so the two relevant ones for the, for the, for this meeting that some of that RM and that VM come from the halo of the Milky Way. 08:37:29 And what's, and also it's not on this diagram, but if you have an intervening galaxy. 08:37:23 You could often get the rotation measure of dispersion measure of that intervening as well. 08:37:29 So until a couple of years ago there were only about a few dozen fast radio bursts, known, but there is now this radio telescope time up here in Canada, that has found more than 1000 fast radio bursts, so we're both building up useful statistics over the entire 08:37:47 sky for the Milky Way halo, and we are also getting enough lines of sight from this and all the telescopes that we are beginning to build up a statistical picture of what sight lines look like as they graze other galaxies, as well. 08:38:03 So, here is just a map from time showing you the distribution too fast radio burst over the sky, and you can see that there are lots and lots of them. 08:38:14 So two things to mention one is is that we, is that we can start to get a crude map of the electron density of the Galactic Halo services from Amanda Cook, who will be hopefully participating in some of this workshop. 08:38:29 This is sort of a smooth map of fast radio bursts over the Milky Way sky. and this isn't right essentially definition, showing you that you can start to see the electron density distribution of the Galactic Halo from fast radio bursts. 08:38:44 I think the thing for discussion right now is how do we maximize information out of these data. There's a lot of observational and statistical and systemic systematic issues that we can. 08:38:57 We need to understand. 08:39:00 We already have a map of the Faraday rotation over the whole sky using background extra galactic sources. So here's a map that's been around for more than 10 years of the rotation measures, but rotation measure gives you a product of and, and they and 08:39:15 they can be hard to disentangle, so there is information on the halo here but you can't tell whether it's electrons or magnetic field or both. 08:39:23 But when we have a dispersion map of the Milky Way from fast radio burst we'll be able to combine the rotation measure in this version measure and separate out maps of electrons, and magnetic field. 08:39:35 So my main interest is in the Milky Way Halo, and how we can use fast radio versatile the traces to map out that that X and others have been doing some very innovative work on how you can use fast radio bursts to probe the halos and other galaxies, as 08:39:50 well. So this is a brand new tool. I think that, as well as actually using the data to extract physics. I hope that over the next eight weeks or in the appropriate sessions there's some discussions on just how to use this tool. 08:40:04 What measurements, do we need, what statistical tools, should we begin using for the data that we already have FRB is a very exciting but they're also a complex tool. 08:40:16 And I think we have a lot to think about in terms of how we use them to learn about halos but I really hope that these can be used along with other traces to say a bunch of new things that we haven't said before, and so there's a halo FRB channel on Slack, 08:40:30 and I believe the leasing discussions about this probably in the in the new probe session later on. Right. 08:40:38 So thank you very much for the impromptu mini tutorial. 08:40:42 There will be a more planned tutorial on Wednesday. If you want to learn more about this. And in fact, even though this topic, might seem 08:40:56 like it belongs in Week eight. 08:40:58 What might we learn from future observations. 08:41:01 We decided to really initiate the discussion now, so it can play out over the whole eight weeks that workshop, rather than just getting around to it in Week eight. 08:41:10 I see some questions coming up in the chat. And what I'm going to do is I'm going to do something. 08:41:19 Maybe. 08:41:22 Well, but I'm tempted to do right here is to say, I'd like you to type those questions into the conversation, so that we can get things going in the conversation, we could surely spend time doing question answering now, but there's some interesting questions 08:41:38 up here, like any evidence for lens FRBs. 08:41:45 And rather than trying to answer them here. I want people to be tempted to go to slack and start talking about it. 08:41:55 So, uh, so yes if you type your question into the chat. I would like you to join the FRB group and type the question in there. 08:42:05 All right, uh, I think we're done with our new conversations. 08:42:15 And the next thing to come up is speed collaboration. 08:42:20 So I'm going to turn the rest of this time slot over to Jess Werk for her to explain what that is. Oh, yeah. 08:42:29 Okay, there's something came up in chat probably worth mentioning threads in slack for people not familiar, I'm, I'm fairly a neophyte in Slack, with one of my other organizers who is more than happy to talk about slack a little bit Mark. 08:42:46 I'll just turn the whole rest of the Monday session over to you. You can talk more about slack. And then segue gracefully into what in the world speed collaboration is. 08:42:59 Thanks, Mark. All right, I'm going to share my screen in a second but sure let's, let's talk a little bit about slack usage. So, one of the most useful features that Stephanie's alluding to is that you can thread, a conversation that is if there's a comment 08:43:15 that you want to reply to you don't have to reply to everyone in that general channel you can reply to that specific comment and it threads it for you and that's a nice way to organize conversations and so I'm becoming more and more appreciative of threads, 08:43:29 as my number of slack teams grow, and you know the messages start to grow and grow and grow so it's a nice way to kind of keep track of things and manage your, your slack. 08:43:40 Another thing I wanted to point out is that to join a channel and maybe, maybe you're not here on a specific day that somebody introduces a channel. You can at least on my browser and I just use slack on chrome I actually haven't downloaded the desktop 08:43:54 application, because I'm a delinquent, but you can you can use those like three dots there are options to browse channels and and you can see all the channels that are available to join, and most of the halo 21 channels that we're creating are completely 08:44:11 open, and so you can just join any of these channels and participate in the conversations threading those conversations, being being mindful to just keep everything organized. 08:44:23 One particular channel I'd like to point out that Mark didn't mention is Halo 21 socializing. 08:44:31 So for those of you who are interested in a more kind of informal, you know get together outside of our plenary zoom times, you can please join Halo 21 socializing I'm going to organize a few events where we can just kind of have fun. 08:44:49 One that I mentioned in Halo 21 socializing is a trivia night and so I'm starting to kind of get some ideas but there are these hosted trivia nights that are supposedly really fun, even on zoom which is actually hard to do I totally get that. 08:45:03 But I've heard that those go really well. 08:45:06 So head over to socializing let me know if you're interested, the pricing on these hosted thing changes whether or not there's going to be based on whether or not there's going to be 50 or more participants so I'm just trying to gauge how much interest. 08:45:19 There is in something like this. 08:45:23 So yeah, please, please, socialize with me outside of normal zoom times and, and I promise if we do a trivia night it won't be a CGM trivia night right there, there will be questions totally outside of that and it's just a way to kind of get to know each 08:45:37 other and connect in a way that's a little different from you know our typical way of doing that. And speaking of connections, I'm going to go ahead and share my screen now. 08:45:50 And just give you an idea of what I'm envisioning for speed collaboration so I posted some speed collaboration. 08:45:59 Previously, always in person. And this is one of those things where you know you get together with a person and have a five minute conversation. And then, in principle, we would do kind of a rotation where we'd be sitting in chairs and then you just move 08:46:13 a chair down and move on to the next person for five minutes but of course we're on zoom now. And so it's going to work a little bit differently. 08:46:23 So just stay tuned for how that's going to go but first of all I just want to tell you the kind of rationale for doing this, which is, you know, we're not in person, but I do think one of the most valuable aspects of being in an in person conference or 08:46:40 workshop is the ability to kind of see people meet somebody one on one and have, you know, a conversation about what you're working on you know what your level of expertise is and maybe come up with some new idea. 08:46:54 Some certainly mutual you know interest and. 08:46:58 And so you know when we're all here on this one zoom window or even in a large group discussion that's not possible. And so speed collaboration is supposed to enable these kinds of one on one connections. 08:47:13 That said, one thing that the organizers talked about and one thing that is absolutely up for debate. If you want on on the general and we're going to be soliciting feedback, every week and so if this doesn't work for people, that's fine. 08:47:27 We're asking for the speed collaboration that participants be of finishing graduate student level or higher that is that you will have obtained your PhD in 2021, or earlier. 08:47:38 And one of the reasons we're going to try to restrict it to people with PhDs or just on the cusp of getting their PhDs, is because we are trying to enable kind of professional level collaboration and a high level sharing of expertise, and we want to be 08:47:52 in a situation where people feel comfortable discussing you know their expertise and I'm just assuming that if you're at the undergraduate level or just beginning at a graduate student, you might find something like this kind of intimidating and. 08:48:08 We're just trying, like I said to limit it to people whose PhDs were awarded in 2021 or earlier the speed collaboration one on ones are not going to be recorded. 08:48:17 These are perfectly private conversations between you and your randomly matched speed collaboration pair so there will be a five, five minute rounds so basically it's 30 minutes, there's one minute for getting out of the zoom Breakout Room going into 08:48:34 another zoom breakout room. 08:48:37 Being prepared so. 08:48:39 And if, if you have to leave, for instance, on the hour at 9am Today I might ask that 9am pacific time, who knows where you are. 08:48:49 Then I might ask that you you know log off before speed collaboration begins today just because that could create a little bit of, you know, disconnect. 08:48:59 And so, um so yeah if you're going to participate in speed collaboration I asked that you be available for the 30 minutes over which the speed collaboration is going to be happening. 08:49:11 And so, after these rounds of one on one conversations will meet up again in this larger group, and we will, you know some of the best ideas something that maybe you got really excited about. 08:49:24 You can come and share back with the group and get some feedback, and just on a personal note, I want to say that I participated in a speed collaboration session at a small workshop that was moderated by Risa Wexler back in. 08:49:38 20- when was that, oh my gosh, who knows, ages ago a million years ago, and I ended up in a conversation with one of my colleagues Alice Decen, who was actually at the same institution is me, although we've never really gotten a chance to talk, and we have 08:49:52 this conversation and it blossomed into what became a successful HST proposal where I'm using these blue horizontal brand stars to look at the circle galactic medium of the Milky Way. 08:50:03 And so I think, you know, there can be exciting things coming out of these be collaborations and I'll say you know for that round of speed collaboration. 08:50:11 I talked with probably six different people. I got one interesting project out of it. Right, not all of them have to be feasible or doable or something to follow up on but it's just an opportunity for new ideas to come out. 08:50:25 So in the first two minutes, you'll probably spend that time introducing yourself. If you need to, if you don't know somebody who you are your institution, what's your expertise, what's your main interest was the last paper you wrote and try to spend 08:50:37 maybe one minute per person. Just kind of describing yourself. 08:50:42 And then, in those last three minutes, you know, work hard to find a common ground interest like what kind of question are you both interested in pursuing and is there some kind of project you could work on together. 08:50:54 Is there some kind of simulation you could design some kind of observations, you might be able to propose. And I think as far as the collaboration goes that this is most fruitful. 08:51:05 When this these projects are ambitious and and novel. 08:51:10 And if you, if you think you've had a really good idea, write it down and come back and share it with the rest of the group when we come back together, and so on the last note I just will say that we're doing this over zoom. 08:51:22 Alright, so I, what I'm going to do functionally and practically is I am going to assign random breakout rooms of two people per room, right, and then I'll end it after five minutes, I'll be timing and, and then we'll come back to the big room and then 08:51:39 I'll assign random breakout rooms again. Now, we noticed this bug when we were kind of testing this method, sometimes random breakout room will randomly assign you to the same person that you already talked to, that is, I guarantee that that will happen 08:51:55 to at least a couple of you right that you'll be in a breakout room again you'll be like crap I already talked to this person. So if that happens if you find yourself in a room with somebody you've already spoken to and you don't want to stay in a room 08:52:06 and continue your conversation which you're perfectly Welcome to do by the way, if it's somebody where you're like wow we had a great conversation this is perfect opportunity to keep talking, fine, but if you want to come back I will be sitting here in 08:52:18 the main room I won't put myself in a breakout room. 08:52:22 And for people who come back in here you can either talk to me in the main room if you're the only one or I'll just send you and whoever else comes back to the general room to a breakout room or you can go and have a speed collaboration. 08:52:35 And so we'll try to see this is kind of experimental, at this point, so we'll try to see if this works out. And so does before before I get started and assigning the breakout rooms, does anybody have any questions about this process. 08:53:00 You can go ahead and unmute yourself for a raise your hand if you have questions. 08:53:08 Stephanie. 08:53:10 Um, yeah hi so if we're not postgraduate students do we just sign up for the next half hour and then sign back in or what should we do, well actually. 08:53:21 Yeah, so, so, um, that's one idea so yeah I'm going to assign randomly to people if, if you want to engage in the larger, you know discussion right after the speed collaboration, you're absolutely Welcome to sign back in, and in 30 minutes but yeah if 08:53:40 you're if you stay here. 08:53:42 you're if you stay here. Um, that means you're going to be assigned to a random breakout mini speed collaboration so I guess at this point I guess I would ask people whose PhDs, are awarded in 2022 or later, you're expecting your he to be awarded 2022 or 08:53:59 later, maybe sign off now and come back in half an hour if you will but before you go We will also announce when this is over on Slack, so you can just stay on slack and and not have to guess like oh I have to be there in 30 minutes because things take 08:54:12 different amounts of time but we'll announce on slack when we're restarting the normal discussion that's going on. 08:54:17 So if you want to rejoin at that point too. Perfect, thanks again, that's a great idea. I think how. 08:54:27 Yeah. So, what should we do if we want to have more discussions I think five minutes is sometimes too short. Right. 08:54:35 That's right. So if you find yourself in a really interesting five minutes be collaboration it's ending after those five minutes, but, you know, you are welcome to contact that person and continue the discussion, you know offline outside of the normal 08:54:49 KITP plenary time so one of the things you might do you know as you're wrapping up your speak collaboration discussion is exchange contact information, or find each other, you know dm each other on the, on the slack page there are a lot of ways to follow 08:55:02 up with an individual, but this is really just supposed to be a start of a conversation. right. 08:55:14 Nice, Stephanie Do you have another question or. 08:55:20 No. Okay. Yeah, so there's also a lower hand feature if you go over to reactions can lower your hand. 08:55:28 Sorry. Yeah, no worries, no it's it's a good, it's a good thing to become familiar with these where we will announce this in slack is in the halo 21 dash announcements channel. 08:55:39 When we're when when we've completed the speed collaboration if if graduate students or undergrads want to rejoin us. 08:55:47 Okay, so we 08:55:52 create. 08:55:56 Looks like we're losing some participants but I expected that that would happen. 08:56:05 And we're about to go so hold on. 08:56:15 How many people do we have here, remaining 72. 08:56:21 Okay. 08:56:23 And if there's like an odd person you find yourself in a breakout room alone. 08:56:28 Come back to the general room. Okay. 08:56:31 I'm hoping that this will, this will work well but, you know, you never, you never know. Okay, so everybody ready, you're about to be assigned to a breakout room. 08:56:46 Let's see if this works. 08:56:54 14.
