Abstract:
We construct evolutionary models of the populations of active galactic
nuclei (AGNs) and supermassive black holes, in which the black hole
mass function grows at the rate implied by the observed luminosity
function, given assumptions about the radiative efficiency and the
luminosity in Eddington units. We draw on a variety of recent X-ray
and optical measurements to estimate the bolometric AGN luminosity
function and compare to X-ray background data and the independent
estimate of Hopkins et al. to assess remaining systematic
uncertainties. The integrated AGN emissivity closely tracks the cosmic
star-formation history, suggesting that star formation and black hole
growth are closely linked at all redshifts.
