The SDSS-IV extended Baryonic Oscillation Spectroscopic Survey: Luminous Red Galaxy Target Selection
Abhishek Prakash, Timothy C. Licquia, Jeffrey A. Newman +26
We describe the algorithm used to select the Luminous Red Galaxy (LRG) sample for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) of the Sloan Digital Sky Survey IV (S…
Ca II Absorbers in the Sloan Digital Sky Survey: Statistics
Gendith M. Sardane, David A. Turnshek, Sandhya M. Rao
We present the results of a survey for CaII 3934,3969 absorption-line systems culled from ~ 95,000 Sloan Digital Sky Survey (SDSS) Data Release 7 and Data Release 9 quasar spectra.…
Thirty-six New, High-Probability, Damped Ly-alpha Absorbers at Redshift 0.42 < z < 0.70
David A. Turnshek, Eric M. Monier, Sandhya M. Rao +3
Quasar damped Ly-alpha (DLA) absorption line systems with redshifts z<1.65 are used to trace neutral gas over approximately 70 per cent of the most recent history of the Universe.…
Probing the Extended Gaseous Regions of M31 with Quasar Absorption Lines
Sandhya Rao, Gendith Sardane, David Turnshek +4
We present HST-COS spectra of ten quasars located behind M31, selected to investigate the properties of gas associated with its extended disk and high velocity clouds (HVCs). The s…
The Pittsburgh Sloan Digital Sky Survey MgII Quasar Absorption-Line Survey Catalog
Anna M. Quider, Daniel B. Nestor, David A. Turnshek +4
We present a catalog of intervening MgII quasar absorption-line systems in the redshift interval 0.36 <= z <= 2.28. The catalog was built from Sloan Digital Sky Survey Data Release…
A Groundbased Imaging Study of Galaxies Causing DLA, subDLA, and LLS Absorption in Quasar Spectra
Sandhya M. Rao, Michele Belfort-Mihalyi, David A. Turnshek +3
We present results from a search for galaxies that give rise to damped Lyman alpha (DLA), subDLA, and Lyman limit system (LLS) absorption at redshifts 0.1 ~< z ~< 1 in the spectra…
Large scale outflows from z ~ 0.7 starburst galaxies identified via ultra-strong MgII quasar absorption lines
Daniel B. Nestor, Benjamin D. Johnson, Vivienne Wild +4
(Abridged) Star formation-driven outflows are a critical phenomenon in theoretical treatments of galaxy evolution, despite the limited ability of observations to trace them across…
Probing star formation across cosmic time with absorption line systems
Brice Ménard, Vivienne Wild, Daniel Nestor +2
We present an empirical connection between cold gas in galactic halos and star formation. Using a sample of more than 8,500 MgII absorbers from SDSS quasar spectra, we report the d…
GALEX Discovery of a Damped Ly-alpha System at Redshift z = 1
Eric Monier, David Turnshek, Sandhya Rao +1
We report the first discovery of a QSO damped Ly-alpha (DLA) system by the GALEX satellite. The system was initially identified as an MgII absorption-line system (z_abs=1.028) in t…
