SDSS-DR3 MgII-based black hole masses
Listed in IVOA Registry (Virtual Observatory)
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.
Description
II/259; superseded by II/294).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 3000{AA}.
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 H{beta} 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.
