On the radiative efficiencies, Eddington ratios, and duty cycles of luminous high-redshift quasars
Francesco Shankar, Martin Crocce, Jordi Miralda-Escude' +2
We investigate the characteristic radiative efficiency ε, Eddington ratio λ, and duty cycle P_0 of high-redshift active galactic nuclei (AGN), drawing on measurements of the AGN lu…
Self-Consistent Models of the AGN and Black Hole Populations: Duty Cycles, Accretion Rates, and the Mean Radiative Efficiency
Francesco Shankar, David H. Weinberg, Jordi Miralda-Escude'
We construct evolutionary models of the populations of AGN and supermassive black holes, in which the black hole mass function grows at the rate implied by the observed luminosity…
Super-massive Black Hole Demography: the Match between the Local and Accreted Mass Functions
F. Shankar, P. Salucci, G. L. Granato +2
We have performed a detailed analysis of the local super-massive black-hole (SMBH) mass function based on both kinematic and photometric data and derived an accurate analytical fit…
