TL;DR: In this article, the authors presented ultraviolet (UV) and optical observations of SN 2009ig, starting about 1 day after explosion until around maximum brightness, and provided a precise measurement of 17.13± 0.07 days for the SN rise time.

TL;DR: In this paper, the authors measured the reverberation lag time of the optical Fe II lines in two Seyfert 1 galaxies, NGC 4593 and Mrk 1511, based on data from a program carried out at Lick Observatory in Spring 2011.
Journal ArticleDOI
The Galaxy Zoo survey for giant AGN-ionized clouds: past and present black hole accretion events
William C. Keel,William C. Keel,S. Drew Chojnowski,S. Drew Chojnowski,Vardha N. Bennert,Vardha N. Bennert,Kevin Schawinski,Chris Lintott,Stuart Lynn,Anna Pancoast,Chelsea E. Harris,Anna Nierenberg,Alessandro Sonnenfeld,Richard Proctor +13 more
TL;DR: In this article, a new set of extended emission-line regions (EELRs) was identified, which can trace both the illumination pattern of escaping radiation and its history over the light-travel time from the active galactic nuclei to the gas.
Journal ArticleDOI
The lick agn monitoring project: recalibrating single-epoch virial black hole mass estimates
Daeseong Park,Jong-Hak Woo,Tommaso Treu,Tommaso Treu,Aaron J. Barth,Misty C. Bentz,Vardha N. Bennert,Vardha N. Bennert,Gabriela Canalizo,Alexei V. Filippenko,Elinor L. Gates,Jenny E. Greene,Matthew A. Malkan,Jonelle L. Walsh +13 more
TL;DR: In this paper, the uncertainties of the single-epoch (SE) method were investigated using homogeneous and high-quality multepoch spectra obtained by the Lick Active Galactic Nucleus (AGN) Monitoring Project for nine local Seyfert 1 galaxies with BH masses <10{sup 8} M{sub Sun }.
Journal ArticleDOI
Cosmic evolution of black holes and spheroids. IV. The M BH - L sph relation
Vardha N. Bennert,Tommaso Treu,Tommaso Treu,Jong-Hak Woo,Jong-Hak Woo,Matthew A. Malkan,Alexandre Le Bris,Alexandre Le Bris,Matthew W. Auger,Sarah C. Gallagher,Roger Blandford +10 more
TL;DR: In this article, the evolution of the M BH-spheroid luminosity (L sph) relation was studied from high-resolution images of 23 Seyfert-1 galaxies at 0.36 and 0.57 obtained with the Near-Infrared Camera and Multi-Object Spectrometer on board the Hubble Space Telescope (HST).
