A seminar led by Scott Duncan Tremaine, as part of the weekly specialized seminars of the Institute of Astrophysics of Paris, on Friday June 12, 2009, at the invitation of Roya Mohayaee-Colin.

Abstract:
The massive black holes discovered at the centers of most galaxies, including ours, are believed to be the ashes of the fuel that powered quasars early in the universe's life. I will briefly review some of the astronomical evidence for these objects and then describe some of the exotic dynamical phenomena that originate in their vicinity, including hypervelocity stars, resonant dynamical relaxation, phase transitions, and unbalanced stellar disks.
