The Cosmic Ultraviolet Baryon Survey (CUBS) IV: The Complex Multiphase Circumgalactic Medium as Revealed by Partial Lyman Limit Systems
Thomas J. Cooper, Gwen C. Rudie, Hsiao-Wen Chen +18
We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density discovered at…
Metal-enriched halo gas across galaxy overdensities over the last 10 billion years
Rajeshwari Dutta, Michele Fumagalli, Matteo Fossati +15
We present a study of metal-enriched halo gas traced by MgII and CIV absorption at z<2 in the MUSE Analysis of Gas around Galaxies survey and the Quasar Sightline and Galaxy Evolut…
Estimating the contribution of foreground halos to the FRB 180924 dispersion measure
Sunil Simha, Nicolas Tejos, J. Xavier Prochaska +6
Fast Radio Burst (FRB) dispersion measures (DMs) record the presence of ionized baryons that are otherwise invisible to other techniques enabling resolution of the matter distribut…
The relationship between gas and galaxies at z<1 using the Q0107 quasar triplet
Alexander Beckett, Simon Morris, Michele Fumagalli +5
We study the distribution and dynamics of the circum- and intergalactic medium using a dense galaxy survey covering the field around the Q0107 system, a unique z~1 projected quasar…
The Cosmic Ultraviolet Baryon Survey (CUBS) -- III. Physical properties and elemental abundances of Lyman limit systems at
Fakhri S. Zahedy, Hsiao-Wen Chen, Thomas M. Cooper +18
(Abridged) We present a systematic investigation of physical conditions and elemental abundances in four optically thick Lyman-limit systems (LLSs) at discovered withi…
MusE GAs FLOw and Wind (MEGAFLOW) VIII. Discovery of a MgII emission halo probed by a quasar sightline
Johannes Zabl, Nicolas F. Bouché, Lutz Wisotzki +11
Using deep (11.2hr) VLT/MUSE data from the MEGAFLOW survey, we report the first detection of extended MgII emission from a galaxy's halo that is probed by a quasar sightline. The M…
