We postulate that supermassive black holes grow in the centers of galaxies until they unbind the galactic gas that feeds them. We show that the corresponding self-regulation condition yields a correlation between black hole mass (Mbh) and galaxy velocity dispersion (σ) as inferred in the local universe and recovers the observed optical and X-ray luminosity functions of quasars at redshifts up to z ~ 6 based on the hierarchical evolution of galaxy halos in a Λ-dominated cold dark matter… Expand

A Unified, Merger-driven Model of the Origin of Starbursts, Quasars, the Cosmic X-Ray Background, Supermassive Black Holes, and Galaxy Spheroids
We present an evolutionary model for starbursts, quasars, and spheroidal galaxies in which mergers between gas-rich galaxies drive nuclear inflows of gas, producing starbursts and feeding the buriedExpand

The Coevolution of Supermassive Black Holes and Massive Galaxies at High Redshift
We exploit the recent, wide samples of far-infrared (FIR) selected galaxies followed up in X-rays and of X-ray/optically selected active galactic nuclei (AGNs) followed up in the FIR band, along withExpand
Dark-ages reionization and galaxy formation simulation - X. The small contribution of quasars to reionization
Motivated by recent measurements of the number density of faint AGN at high redshift, we investigate the contribution of quasars to reionization by tracking the growth of central supermassive blackExpand
Energy input from quasars regulates the growth and activity of black holes and their host galaxies
TLDR
Simulations that simultaneously follow star formation and the growth of black holes during galaxy–galaxy collisions find that, in addition to generating a burst of star formation, a merger leads to strong inflows that feed gas to the supermassive black hole and thereby power the quasar. Expand
Photon trapping enables super-Eddington growth of black hole seeds in galaxies at high redshift
We identify a physical mechanism that would have resulted in rapid, obscured growth of seed supermassive black holes in galaxies at z 6. Specifically, we find that the density at the centre ofExpand
