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

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

We investigate the relationship between black hole mass, M_\mathrm{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_\mathrm{BH}, from the broad H\beta line width and the bulge stellar velocity dispersion (\sigma_*) from the [{\sc O iii}] narrow line width (\sigma_{\mathrm{[O~III}]}). The results agree in the mean with the M_\mathrm{BH}---\sigma_*, relationship for nearby galaxies. Use of Mg {\sc ii} and [{\sc O ii}] in place of H\beta and [{\sc O iii}] allows work at redshifts up to z ~1. This work is supported by the Texas Advanced Research Program under grant 003658-0177-2001.
