The Black Hole Masses of High-Redshift Quasars
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 $z\sim2.5$ from optical spectra alone.
