[60.05] The Black Hole Mass - Galaxy Bulge Relationship for QSOs in the SDSS DR1

S. Salviander, G.A. Shields, K. Gebhardt (Univ. of Texas at Austin)

We investigate the relationship between black hole mass, M\rm BH, and host galaxy velocity dispersion for QSOs in Data Release 1 (DR1) of the Sloan Digital Sky Survey (SDSS) (www.sdss.org) using an automated spectrum fitting routine. We derive M\rm BH, from the broad H\beta line width and the bulge stellar velocity dispersion (\sigma*) from the [O III] narrow line width (\sigma\rm [O~III]). The results agree in the mean with the M\rm BH---\sigma*, relationship for nearby galaxies. Use of Mg II and [O II] in place of H\beta and [O III] allows an assessment of the evolution of the M\rm BH---\sigma* relationship at redshifts up to z ~ 1.2.
