The Black Hole Mass-Bulge Luminosity Relationship for Active Galactic Nuclei from Reverberation Mapping and Hubble Space Telescope Imaging
Misty C. Bentz, Bradley M. Peterson, Richard W. Pogge +1
We investigate the relationship between black hole mass and bulge luminosity for AGNs with reverberation-based black hole mass measurements and bulge luminosities from two-dimensio…
The Radius-Luminosity Relationship for Active Galactic Nuclei: The Effect of Host-Galaxy Starlight on Luminosity Measurements II. The Full Sample of Reverberation-Mapped AGNs
Misty C. Bentz, Bradley M. Peterson, Hagai Netzer +2
We present high-resolution HST images of all 35 AGNs with optical reverberation-mapping results, which we have modeled to create a nucleus-free image of each AGN host galaxy. From…
Systematic Uncertainties in Black Hole Masses Determined from Single Epoch Spectra
Kelly D. Denney, Bradley M. Peterson, Matthias Dietrich +2
We explore the nature of systematic errors that can arise in measurement of black hole masses from single-epoch spectra of active galactic nuclei (AGNs) by utilizing the many epoch…
First Results from the Lick AGN Monitoring Project: The Mass of the Black Hole in Arp 151
Misty C. Bentz, Jonelle L. Walsh, Aaron J. Barth +24
We have recently completed a 64-night spectroscopic monitoring campaign at the Lick Observatory 3-m Shane telescope with the aim of measuring the masses of the black holes in 13 ne…
Dynamical Constraints on The Masses of the Nuclear Star Cluster and Black Hole in the Late-Type Spiral Galaxy NGC 3621
A. J. Barth, L. E. Strigari, M. C. Bentz +2
NGC 3621 is a late-type (Sd) spiral galaxy with an active nucleus, previously detected through mid-infrared [Ne V] line emission. Archival Hubble Space Telescope (HST) images revea…
The Mass of the Black Hole in the Quasar PG 2130+099
C. J. Grier, B. M. Peterson, M. C. Bentz +14
We present the results of a recent reverberation-mapping campaign undertaken to improve measurements of the radius of the broad line region and the central black hole mass of the q…
An Offset Seyfert 2 Nucleus in the Minor Merger System NGC 3341
A. J. Barth, M. C. Bentz, J. E. Greene +1
We present the discovery of a triplet of emission-line nuclei in the disturbed disk galaxy NGC 3341, based on archival data from the Sloan Digital Sky Survey and new observations f…
First Stellar Velocity Dispersion Measurement of a Luminous Quasar Host with Gemini North Laser Guide Star Adaptive Optics
Linda C. Watson, Paul Martini, Kalliopi M. Dasyra +5
We present the first use of the Gemini North laser guide star adaptive optics (LGS AO) system and an integral field unit (IFU) to measure the stellar velocity dispersion of the hos…
Hubble Space Telescope Imaging of Bright Lyman-break Galaxy Candidates from the Sloan Digital Sky Survey: Not LBGs After All
Misty C. Bentz, Richard W. Pogge, Patrick S. Osmer
We present deep Hubble Space Telescope ACS and NICMOS images of six bright Lyman-break galaxy candidates that were previously discovered in the Sloan Digital Sky Survey. We find th…
