2004ApJ...615..645O Supermassive Black Holes in Active Galactic Nuclei. II. Calibration of the Black Hole Mass -- Velocity Dispersion Relationship for Active Galactic Nuclei Christopher A. Onken, Laura Ferrarese, David Merritt, Bradley M. Peterson, Richard W. Pogge, Marianne Vestergaard, and Amri Wandel Abstract. We calibrate reverberation-based black hole (BH) masses in active galactic nuclei (AGNs) by using the correlation between BH mass, M_BH_, and bulge/spheroid stellar velocity dispersion, {sigma}_*_. We use new measurements of {sigma}_*_ for six AGNs and published velocity dispersions for 10 others, in conjunction with improved reverberation-mapping results, to determine the scaling factor required to bring reverberation-based BH masses into agreement with the quiescent galaxy M_BH_-{sigma}_*_ relationship. The scatter in the AGN BH masses is found to be less than a factor of 3. The current observational uncertainties preclude the use of the scaling factor to discriminate between broad-line region models.
