Space Telescope and Optical Reverberation Mapping Project. X. Understanding the Absorption-Line Holiday in NGC 5548

M. Dehghanian, G. J. Ferland, G. A. Kriss +27

The flux variations in the emission lines in active galactic nuclei (AGNs) are driven by variations in the ionizing continuum flux --which are usually reflected in the observable U…

Active Galaxy Science in the LSST Deep-Drilling Fields: Footprints, Cadence Requirements, and Total-Depth Requirements

W. N. Brandt, Q. Ni, G. Yang +25

This white paper specifies the footprints, cadence requirements, and total-depth requirements needed to allow the most-successful AGN studies in the four currently selected LSST De…

The First Swift Intensive AGN Accretion Disk Reverberation Mapping Survey

R. Edelson, J. Gelbord, E. Cackett +32

Swift intensive accretion disk reverberation mapping of four AGN yielded light curves sampled 200-350 times in 0.3-10 keV X-ray and six UV/optical bands. Uniform reduction an…

The Berkeley Sample of Stripped-Envelope Supernovae

Isaac Shivvers, Alexei V. Filippenko, Jeffrey M. Silverman +22

We present the complete sample of stripped-envelope supernova (SN) spectra observed by the Lick Observatory Supernova Search (LOSS) collaboration over the last three decades: 888 s…

The Lick AGN Monitoring Project 2011: Dynamical Modeling of the Broad-Line Region

Peter R. Williams, Anna Pancoast, Tommaso Treu +22

We present models of the H-emitting broad-line region (BLR) in seven Seyfert 1 galaxies from the Lick AGN (Active Galactic Nucleus) Monitoring Project 2011 sample, drawing infer…

Serendipitous Discovery of a 14-year-old Supernova at 16 Mpc

James Guillochon, Jorge Stockler de Moraes, Matt Nicholl +5

In this Research Note we present a serendipitous discovery of the transient CGS2004A (AT2004iu) in an image collected by the Carnegie-Irvine Galaxy Survey of the Scd: galaxy NGC 18…
