Abstract: Lecturer compares current estimates of the mass density in supermassive black holes to the quasar era, using dynamical mass estimates in local quiescent galaxies, reverberation mapping in active galaxies and quasars, and estimates of the mean density of compact objects based on quasar optical counts and observations of the X-ray background. Also discusses how observations can be used to learn about the formation and evolution of black holes and of the host stellar systems.
