Neutral-Gas-Phase Metal Abundances in ZnII-Selected Quasar Absorption Line Systems near Redshift
Eric M. Monier, David A. Turnshek, Sandhya M. Rao +2
We present ten metallicity measurements for quasar absorbers near that were selected for having unusually significant ZnII absorption in their SDSS spectra. Follow-up UV sp…
The Statistical Properties of Neutral Gas at z<1.65 from UV Measurements of Damped Lyman Alpha Systems
Sandhya M. Rao, David A. Turnshek, Gendith M. Sardane +1
We derive the statistical properties of neutral gas at redshifts 0.11<z<1.65 from UV measurements of quasar Lyman alpha absorption lines corresponding to 369 MgII systems with $W^{…
A study of the circum-galactic medium at z ~ 0.6 using DLA-galaxies
Hadi Rahmani, Celine Peroux, David A. Turnshek +5
We present the study of a sample of nine QSO fields, with damped-Ly-alpha (DLA) or sub-DLA systems at z~0.6, observed with the X-Shooter spectrograph at the Very Large Telescope. B…
The ESO UVES Advanced Data Products Quasar Sample - VI. Sub-Damped Lyman- Metallicity Measurements and the Circum-Galactic Medium
S. Quiret, C. Péroux, T. Zafar +8
The Circum-Galactic Medium (CGM) can be probed through the analysis of absorbing systems in the line-of-sight to bright background quasars. We present measurements of the metallici…
Luminous Red Galaxies: Selection and classification by combining optical and infrared photometry
Abhishek Prakash, Timothy C. Licquia, Jeffrey A. Newman +1
We describe a new method of combining optical and infrared photometry to select Luminous Red Galaxies (LRGs) at redshifts . We explore this technique using a combination o…
CaII Absorbers in the Sloan Digital Sky Survey: Element Abundances and Dust
Gendith M. Sardane, David A. Turnshek, Sandhya M. Rao
We present measurements of element abundance ratios and dust in CaII~absorbers identified in SDSS DR7+DR9. In an earlier paper we formed a statistical sample of 435 CaII absorbers…
