Observation of Eclipse Shadow Bands Using High Altitude Balloon and Ground-Based Photodiode Arrays

Janvi P. Madhani, Grace E. Chu, Carlos Vazquez Gomez +7

The results of an investigation into whether or not eclipse shadow bands have an atmospheric origin are presented. Using high altitude balloon and ground-based photodiode arrays du…

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…

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…
