Supermassive Black Holes in Active Galactic Nuclei. II. Calibration of the Black Hole Mass-Velocity Dispersion Relationship for Active Galactic Nuclei
We calibrate reverberation-based black hole (BH) masses in active galactic nuclei (AGNs) by using the correlation between BH mass, M sub(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...

| description | We calibrate reverberation-based black hole (BH) masses in active galactic nuclei (AGNs) by using the correlation between BH mass, M sub(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 sub(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. |
