The Sloan Digital Sky Survey quasar catalog: tenth data release
Isabelle Pâris, Patrick Petitjean, Éric Aubourg +47
We present the Data Release 10 Quasar (DR10Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS obj…
Galaxies with Background QSOs: II. An Automated Search for Multiple Galaxy Emission Lines
Lorrie Straka, Zakary L. Whichard, Varsha P. Kulkarni +4
We have improved upon our previous search technique of systematically searching QSO spectra for narrow galactic H-alpha emission, which indicates a foreground galaxy within the Slo…
Photometry of Variable Stars from Dome A, Antarctica: Results from the 2010 Observing Season
Lingzhi Wang, Lucas M. Macri, Lifan Wang +17
We present results from a season of observations with the Chinese Small Telescope ARray (CSTAR), obtained over 183 days of the 2010 Antarctic winter. We carried out high-cadence ti…
Probing the Circumgalactic Medium at High-Redshift Using Composite BOSS Spectra of Strong Lyman-alpha Forest Absorbers
Matthew M. Pieri, Michael J. Mortonson, Stephan Frank +17
We present composite spectra constructed from a sample of 242,150 Lyman-alpha (Lya) forest absorbers at redshifts 2.4<z<3.1 identified in quasar spectra from the Baryon Oscillation…
Candidate Type II Quasars at 2 < z < 4.3 in the Sloan Digital Sky Survey III
Rachael Alexandroff, Michael A. Strauss, Jenny E. Greene +12
At low redshifts, dust-obscured quasars often have strong yet narrow permitted lines in the rest-frame optical and ultraviolet, excited by the central active nucleus, earning the d…
Narrow absorption line variability in repeat quasar observations from the Sloan Digital Sky Survey
Troy L. Hacker, Robert J. Brunner, Britt F. Lundgren +1
We present the results from a time domain study of absorption lines detected in quasar spectra with repeat observations from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7).…
