The Black Hole Mass-Galaxy Bulge Relationship for QSOs in the Sloan Digital Sky Survey Data Release 3

We investigate the relationship between black hole mass, MBH, and host galaxy velocity dispersion, sigma*, for QSOs in Data Release 3 of the Sloan Digital Sky Survey. We derive MBH from the broad Hbeta line width and continuum luminosity and the bulge stellar velocity dispersion from the narrow [O I...

Description
Summary:We investigate the relationship between black hole mass, MBH, and host galaxy velocity dispersion, sigma*, for QSOs in Data Release 3 of the Sloan Digital Sky Survey. We derive MBH from the broad Hbeta line width and continuum luminosity and the bulge stellar velocity dispersion from the narrow [O III] line width (sigma[OIII]). At higher redshifts, we use Mg II and [O II] in place of Hbeta and [O III]. For redshifts z
