Crystal Martin (UCSB), Evolution of Galactic Winds

Schedule Aug 17, 2007 Evolution of Galactic Winds Crystal Martin (UCSB)

For some time now, we have seen overwhelming evidence that supernovae explosions in starburst galaxies drive significant amounts of metals out of galactic disks. The difficult question has been determining how far away from a galaxy these metals go. I will present new measurements of the size (and size evolution) of metal-enriched regions in the IGM and discuss their relation to starburst winds. I will attempt to synthesize these results with our direct knowledge of the wind dynamics in local starburst galaxies.
