An Improved Method for Using MgII to Estimate Black Hole Masses in Active Galactic Nuclei
Christopher A. Onken, Juna A. Kollmeier
We present a method for obtaining accurate black hole (BH) mass estimates from the MgII emission line in active galactic nuclei (AGNs). Employing the large database of AGN measurem…
The Black Hole Mass of NGC 4151: Comparison of Reverberation Mapping and Stellar Dynamical Measurements
Christopher A. Onken, Monica Valluri, Bradley M. Peterson +11
We present a stellar dynamical estimate of the black hole (BH) mass in the Seyfert 1 galaxy, NGC 4151. We analyze ground-based spectroscopy as well as imaging data from the ground…
The Mass of the Black Hole in the Seyfert 1 Galaxy NGC 4593 from Reverberation Mapping
Kelly D. Denney, Misty C. Bentz, Bradley M. Peterson +15
We present new observations leading to an improved black hole mass estimate for the Seyfert 1 galaxy NGC 4593 as part of a reverberation-mapping campaign conducted at the MDM Obser…
A Reverberation-Based Mass for the Central Black Hole in NGC 4151
Misty C. Bentz, Kelly D. Denney, Edward M. Cackett +15
We have undertaken a new ground-based monitoring campaign to improve the estimates of the mass of the central black hole in NGC 4151. We measure the lag time of the broad H beta li…
The Radius-Luminosity Relationship for Active Galactic Nuclei: The Effect of Host-Galaxy Starlight on Luminosity Measurements
Misty C. Bentz, Bradley M. Peterson, Richard W. Pogge +2
We have obtained high resolution images of the central regions of 14 reverberation-mapped active galactic nuclei (AGN) using the Hubble Space Telescope Advanced Camera for Surveys…
Central Masses and Broad-Line Region Sizes of Active Galactic Nuclei. II. A Homogeneous Analysis of a Large Reverberation-Mapping Database
B. M. Peterson, L. Ferrarese, K. M. Gilbert +9
We present improved black hole masses for 35 active galactic nuclei (AGNs) based on a complete and consistent reanalysis of broad emission-line reverberation-mapping data. From obj…
