Faint LAEs near z>4.7 CIV absorbers revealed by MUSE
C. Gonzalo Diaz, Emma Ryan-Weber, Wouter Karman +5
We present the results from the search for Lyman Alpha emitters (LAEs) in the proximity of 11 CIV absorption systems at in the spectrum of the QSO J1030+0524, using data…
Exploring the origins of a new, apparently metal-free gas cloud at z = 4.4
P. Frédéric Robert, Michael T. Murphy, John M. O'Meara +2
We report the discovery and analysis of only the third Lyman-limit system in which a high-quality resolution, echelle spectrum reveals no metal absorption lines, implying a metalli…
Imprints of the first billion years: Lyman limit systems at
Neil H. M. Crighton, J. Xavier Prochaska, Michael T. Murphy +3
Lyman Limit systems (LLSs) trace the low-density circumgalactic medium and the most dense regions of the intergalactic medium, so their number density and evolution at high redshif…
The CGM and IGM at z5: metal budget and physical connection
Alex Codoreanu, Emma V. Ryan-Weber, Luz Ángela García +5
We present further results of a survey for absorption line systems in the spectra of four high redshift quasars (5.79 z 6.13) obtained with the ESO Very…
Galaxies Probing Galaxies in PRIMUS - II. The Coherence Scale of the Cool Circumgalactic Medium
Kate H. R. Rubin, Aleksandar M. Diamond-Stanic, Alison L. Coil +2
The circumgalactic medium (CGM) close to ~L* star-forming galaxies hosts strong MgII 2796 absorption (with equivalent width W_2796>0.1 Ang) with a near-unity covering fraction. To…
Galaxies Probing Galaxies in PRIMUS - I. Sample, Spectroscopy, and Characteristics of the z~0.5 MgII-Absorbing Circumgalactic Medium
Kate H. R. Rubin, Aleksandar M. Diamond-Stanic, Alison L. Coil +2
Spectroscopy of background QSO sightlines passing close to foreground galaxies is a potent technique for studying the circumgalactic medium (CGM). QSOs are effectively point source…
