J/ApJ/690/20    Models of the AGN and black hole populations    (Shankar+, 2009)

Self-consistent models of the AGN and black hole populations: duty cycles, accretion rates, and the mean radiative efficiency. Shankar F., Weinberg D.H., Miralda-Escude J. <Astrophys. J., 690, 20-41 (2009)> =2009ApJ...690...20S
ADC_Keywords: Models, evolutionary ; Active gal. nuclei ; Redshifts Keywords: cosmology: theory - galaxies: evolution - quasars: general 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. File Summary:
