Empirical Constraints of Super-Galactic Winds at z >= 0.5
Jean-Rene Gauthier, Hsiao-Wen Chen
(Abridged) Under the hypothesis that MgII absorbers found near the minor axis of a galaxy originate in the cool phase of winds, we carry out a study to constrain the properties of…
Probing the IGM/Galaxy Connection V: On the Origin of Lya and OVI Absorption at z<0.2
J. Xavier Prochaska, B. Weiner, H. -W. Chen +2
We analyze the association of galaxies to Lya and OVI absorption, the most commonly detected transitions in the low-z intergalactic medium (IGM), in the fields of 14 quasars with z…
Probing the IGM/Galaxy Connection IV: The LCO/WFCCD Galaxy Survey of 20 Fields Surrounding UV Bright Quasars
J. Xavier Prochaska, B. Weiner, H. -W. Chen +2
We publish the survey for galaxies in 20 fields containing ultraviolet bright quasars (with z_em 0.1 to 0.5) that can be used to study the association between galaxies and absorpti…
The Clustering of MgII Absorption Systems at z=0.5 and Detection of Cold Gas in Massive Halos
Jean-Rene Gauthier, Hsiao-Wen Chen, Jeremy L. Tinker
We measure the large-scale clustering of MgII λλ2796,2803 absorbers with respect to a population of luminous red galaxies (LRGs) at z \sim 0.5. From the cross-correlation measureme…
