Abstract:
We present MgII-based black hole (BH) mass estimates for 27602 quasars
with rest-frame UV spectra available in the Sloan Digital Sky Survey
Data Release Three (Cat. II/259; superseded by II/294). This
estimation is possible due to the existence of an empirical
correlation between the radius of the broad-line region (BLR) and the
continuum luminosity at 3000Å. We regenerate this correlation by
applying our measurement method to UV spectra of low-redshift quasars
in the Hubble Space Telescope/International Ultraviolet Explorer
databases which have corresponding reverberation mapping estimates of
the Hβ BLR's radius. Our mass estimation method uses the line
dispersion rather than the full width at half-maximum of the
low-ionization MgII emission line.
