Quasar Mass Functions Across Cosmic Time

Published 15 Jul 2010 in astro-ph.CO | (1007.2600v1)

Abstract: I present mass functions of actively accreting black holes detected in different quasar surveys which in concert cover a wide range of cosmic history. I briefly address what we learn from these mass functions. I summarize the motivation for such a study and the methods by which we determine black hole masses.
