Black Hole - Bulge Relationship of Post-Starburst Quasars at z \sim 0.3

Abstract

The MBH - σ\ast relation has been studied extensively for local galaxies, but to date there have been scarce few direct measurements of stellar velocity dispersions for systems beyond the local universe. We investigate black hole and host galaxy properties of six "post-starburst quasars" at z \sim 0.3. Spectra of these objects simultaneously display features from the active nucleus including broad emission lines and a host galaxy Balmer absorption series indicative of the post-starburst stellar population. These are the first measurements of σ\ast in such objects, and we significantly increase the number of directly-measured non-local objects on the MBH - σ\ast diagram. The "post-starburst quasars" of our sample fall on or above the locally defined MBH - σ\ast relation, a result that is consistent with previous MBH - σ\ast studies of samples at z > 0.1. However, they are generally consistent with the MBH-Lbulge relation. Futhermore, their location on the Faber-Jackson relation suggests that some of the bulges may be dynamically peculiar.
