Dynamics of Black Holes and Binaries Near Sgr A*
Dr. Eric Pfahl, University of Virginia

Of order 104 stellar-mass black holes may reside within 1 pc of Sgr A*, driven there by dynamical friction. If a substantial number of binaries populate our Galactic nucleus, some fraction of the stellar black holes may acquire companions as a result of binary-single exchange interactions. Such a binary may capture a second black hole in a subsequent exchange. I will describe encouraging preliminary results on the dynamical production of black-hole binaries in the Galactic center, addressing these objects as potential sources of X-rays and gravitational radiation.
