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…

NGC 5548 in a Low-Luminosity State: Implications for the Broad-Line Region

Misty C. Bentz, Kelly D. Denney, Edward M. Cackett +15

We describe results from a new ground-based monitoring campaign on NGC 5548, the best studied reverberation-mapped AGN. We find that it was in the lowest luminosity state yet recor…
