[37.04] Prospects for Detecting Gravitational Radiation from Supermassive Black Holes

D. Richstone (University of Michigan)

An analysis of 25 galaxies suggests that approximately all galaxies host massive (106 to 109 Msolar) black holes. If this is the case, these objects must play a major role in the formation and evolution of galaxies. This population of massive black holes in the present universe is consistent with the masses and numbers of bh predicted by the luminosity function of quasars in the z \gtrsim 2 universe.

These objects merge. Although the merger rates are uncertain, the gravitational radiation expected from lower mass objects (black holes in the mass range 105 - 107 Msolar) is likely to be easily observatble with LISA, a proposed NASA/ESA mission.

This research was supported by NASA.
