The Black Hole Masses of High-Redshift Quasars
نویسندگان
چکیده
A reliable method for estimating the black-hole masses of high-redshift quasars would provide crucial new information for understanding the nature and cosmological evolution of quasars. In this proceedings we summarize the results of our recent paper (McLure & Jarvis 2002) which provides a virial black-hole mass estimator based on rest-frame UV observables, thereby allowing reliable black-hole mass estimates to be obtained out to redshifts of z ∼ 2.5 from optical spectra alone. All cosmological calculations assume Ωm = 0.3,Λ = 0.7,H0 = 70 kms−1Mpc−1. 1.

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 to quasars at lower redshift. It is shown that the central black holes in luminous z > ∼ 4 quasars are very massive ( ∼ 10M⊙). It is argued that the mass estimates of the high-z quasars are not subje...
متن کاملQuasar Hosts and the Black Hole-Spheroid Connection
I review our current understanding of the structures and ages of the host galaxies of quasars, and the masses of their central black holes. At low redshift, due largely to the impact of the Hubble Space Telescope, there is now compelling evidence that the hosts of quasars with MV < −24 mag are virtually all massive ellipticals, with basic properties indistinguishable from those displayed by the...
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 کاملDetermining Central Black Hole Masses in Distant Active Galaxies
An empirical relationship, of particular interest for studies of high redshift active galactic nuclei (AGNs) and quasars, between the masses of their central black-holes and rest-frame ultraviolet (UV) parameters measured in single-epoch AGN spectra is presented. This relationship is calibrated to recently measured reverberation masses of low-redshift AGNs and quasars. An empirical relationship...
متن کاملMeasuring the black hole masses of high redshift quasars
A new technique is presented for determining the black-hole masses of high-redshift quasars from optical spectroscopy. The new method utilizes the full-width half maximum (FWHM) of the low-ionization Mgii emission line and the correlation between broad-line region (BLR) radius and continuum luminosity at 3000Å. Using archival UV spectra it is found that the correlation between BLR radius and 30...
