The Lick AGN Monitoring Project: Recalibrating Single-Epoch Virial Black Hole Mass Estimates
Daeseong Park, Jong-Hak Woo, Tommaso Treu +9
We investigate the calibration and uncertainties of black hole mass estimates based on the single-epoch (SE) method, using homogeneous and high-quality multi-epoch spectra obtained…
Very Early Ultraviolet and Optical Observations of the Type Ia Supernova 2009ig
Ryan J. Foley, P. J. Challis, A. V. Filippenko +18
Supernova (SN) 2009ig was discovered 17 hours after explosion by the Lick Observatory Supernova Search, promptly classified as a normal Type Ia SN (SN Ia), peaked at V = 13.5 mag,…
The Lick AGN Monitoring Project 2011: Reverberation Mapping of Markarian 50
A. J. Barth, A. Pancoast, S. J. Thorman +46
The Lick AGN Monitoring Project 2011 observing campaign was carried out over the course of 11 weeks in Spring 2011. Here we present the first results from this program, a measureme…
The Galaxy Zoo survey for giant AGN-ionized clouds: past and present black-hole accretion events
William C. Keel, S. Drew Chojnowski, Vardha N. Bennert +8
Some active galactic nuclei (AGN) are surrounded by extended emission-line regions (EELRs), which trace both the illumination pattern of escaping radiation and its history over the…
Hubble Space Telescope Imaging of Post-Starburst Quasars
S. L. Cales, M. S. Brotherton, Zhaohui Shang +7
We present images of 29 post-starburst quasars (PSQs) from a Hubble Space Telescope (\emph{HST}) Advanced Camera for Surveys (ACS) Wide Field Channel Snapshot program. These broad-…
The Mass of the Black Hole in Arp 151 from Bayesian Modeling of Reverberation Mapping Data
Brendon J. Brewer, Tommaso Treu, Anna Pancoast +7
Supermassive black holes are believed to be ubiquitous at the centers of galaxies. Measuring their masses is extremely challenging yet essential for understanding their role in the…
