High redshift quasars and the supermassive black hole mass budget: constraints on quasar formation models
We investigate the constraints on models of supermassive black hole (SMBH) and quasar formation obtainable from two recent observational developments: the discovery of luminous quasars at z ∼ 6, and estimates of the local mass density of SMBHs. If ∼ 90 per cent of this mass was accreted at redshifts z < ∼ 3, as suggested by the observed quasar luminosity functions, these joint constraints pose ...
متن کاملProperties of high-redshift quasars – I. Evolution of the supermassive black hole to halo mass ratio
In the local universe, the masses of Super-Massive Black-Holes (SMBH) appear to correlate with the physical properties of their hosts, including the mass of the dark-matter halos. At higher redshifts, we observe the growth of SMBHs indirectly through the identification of high redshift quasars. However information on their hosts is more difficult to obtain. In this paper we determine the masses...
متن کاملModeling the Counts of Faint Radio Loud Quasars: Constraints on the Supermassive Black Hole Population and Predictions for High Redshift
We use a physically motivated semi–analytic model, based on the mass function of dark matter halos, to predict the number of radio–loud quasars as a function of redshift and luminosity. Simple models in which the central BH mass scales with the velocity dispersion of its host halo as Mbh ∝ σ5 halo have been previously found to be consistent with a number of observations, including the optical a...
متن کاملBlack Hole Masses of High-redshift Quasars
Black-hole masses of distant quasars cannot be measured directly, but can be estimated to within a factor 3 to 5 using scaling relationships involving the quasar luminosity and broad-line width. Why such relationships are reasonable is summarized. The results of applying scaling relationships to data of quasars at a range of redshifts (z ≤ 6.3) are presented. Luminous quasars typically have mas...
متن کاملA Relation between Supermassive Black Hole Mass and Quasar Metallicity?
We analyze spectra for a large sample of 578 Active Galactic Nuclei to examine the relationships between broad emission line properties and central supermassive black hole (SMBH) mass. We estimate SMBH masses by applying the virial theorem to the C IV λ1549 broad emission line. Although the FWHMs of C IV and Hβ appear nearly unrelated in individual objects, these FWHMs are well correlated when ...
