We demonstrate that the luminosity function of the recently detected population of actively star-forming galaxies at redshift z = 3 and the B-band luminosity function of quasi-stellar objects (QSOs) at the same redshift can both be matched with the mass function of dark matter haloes predicted by standard variants of hierarchical cosmogonies for lifetimes of optically bright QSOs anywhere in the range 106 to 108 yr. There is a strong correlation between the lifetime and the required degree of…

ON THE EVOLUTION OF HIGH-REDSHIFT ACTIVE GALACTIC NUCLEI
We build a simple physical model to study the high-redshift active galactic nucleus (AGN) evolution within the co-evolution framework of central black holes (BHs) and their host galaxies. The
Self-regulated Growth of Supermassive Black Holes in Galaxies as the Origin of the Optical and X-Ray Luminosity Functions of Quasars
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
A simple model for the evolution of supermassive black holes and the quasar population
An empirically motivated model is presented for accretion-dominated growth of the super massive black holes (SMBH) in galaxies, and the implications are studied for the evolution of the quasar
Black Holes, Galaxy Formation, and the MBH-σ Relation
Recent X-ray observations of intense high-speed outflows in quasars suggest that supercritical accretion on to the central black hole may have an important effect on a host galaxy. I revisit some
Quasars and galaxy formation
Quasars are widely believed to be powered by accretion onto supermassive black holes and there is now considerable evidence for a link between mergers, the activity of quasars and the formation of
Early Growth and Efficient Accretion of Massive Black Holes at High Redshift
Black hole masses of the highest redshift quasars (4 ≲ z ≲ 6) are estimated using a previously presented scaling relationship, derived from reverberation mapping of nearby quasars, and compared with
Observational constraints on growth of massive black holes
We study the observational constraints on the growth of massive black holes (BHs) in galactic nuclei. We use the velocity dispersions of early-type galaxies obtained by the Sloan Digital Sky Survey
A Physical Model for the Luminosity Function of High-Redshift Quasars
We provide a simple theoretical model for the quasar luminosity function at high redshifts that naturally reproduces the statistical properties of the luminous Sloan Digital Sky Survey (SDSS) quasar
The Merger History of Supermassive Black Holes in Galaxies
The ubiquity of supermassive black holes (SMBHs) at the centers of nearby luminous galaxies can arise from the multiple mergers experienced by dark matter halos in hierarchical structure formation
Timing the starburst–AGN connection
The mass of supermassive black holes at the centre of galaxies is tightly correlated with the mass of the galaxy bulges which host them. This observed correlation implies a mechanism of joint growth,
