Journal ArticleDOI
Atlas of quasar energy distributions
Martin Elvis,Belinda Jane Wilkes,Jonathan C. McDowell,Richard F. Green,Jill Bechtold,Steven P. Willner,M. S. Oey,M. S. Oey,Elisha Polomski,Elisha Polomski,Roc Cutri +10 more
TL;DR: In this article, the spectral energy distributions (SEDs) of normal, nonblazar, quasars over the whole available range (radio to 10 keV X-rays) of the electromagnetic spectrum are presented.
Journal ArticleDOI
Are the Variations in Quasar Optical Flux Driven by Thermal Fluctuations
TL;DR: In this article, a sample of optical light curves for 100 quasars, 70 of which have black hole mass estimates, was used to estimate the characteristic timescale and amplitude of flux variations; their approach is not affected by biases introduced from discrete sampling effects.
Journal ArticleDOI
Discovery of the Dust-Enshrouded Progenitor of SN 2008S with Spitzer
J. L. Prieto,Matthew D. Kistler,Todd A. Thompson,Hasan Yuksel,Christopher S. Kochanek,Krzysztof Z. Stanek,John F. Beacom,Paul Martini,Anna Pasquali,Jill Bechtold +9 more
TL;DR: In this paper, the progenitor of the recent Type IIn SN 2008S in the nearby galaxy NGC 6946 was found in deep, preexplosion optical images of its host galaxy, but only through examination of archival Spitzer mid-IR data.
Journal ArticleDOI
The discovery of Segue 2: a prototype of the population of satellites of satellites
Vasily Belokurov,Matthew G. Walker,Nick Evans,Gerry Gilmore,Mike Irwin,Mario Mateo,Lucio Mayer,Edward W. Olszewski,Jill Bechtold,T. Pickering +9 more
TL;DR: In this paper, a new Milky Way satellite Segue 2 was found in the data of the Sloan Extension for Galactic Understanding and Exploration (SEGUE), followed by deeper imaging and spectroscopy on the Multiple Mirror Telescope (MMT).
Journal ArticleDOI

TL;DR: In this paper, a large-scale ground-based optical spectroscopy and photometry of the variable Seyfert 1 galaxy NGC 5548 undertaken in support of an IUE monitoring campaign is described.
