A Complex Multiphase DLA Associated with a Compact Group at z=2.431 Traces Accretion, Outflows, and Tidal Streams
Nikole M. Nielsen, Glenn G. Kacprzak, Sameer +4
As part of our program to identify host galaxies of known z=2-3 MgII absorbers with the Keck Cosmic Web Imager (KCWI), we discovered a compact group giving rise to a z=2.431 DLA wi…
Examining quasar absorption-line analysis methods: the tension between simulations and observational assumptions key to modelling clouds
Rachel Marra, Christopher W. Churchill, Glenn G. Kacprzak +3
A key assumption in quasar absorption line studies of the circumgalactic medium (CGM) is that each absorption component maps to a spatially isolated "cloud" structure that has sing…
Probing the physicochemical properties of the Leo Ring and the Leo I group
Sameer, Jane Charlton, Glenn Kacprzak +6
We present an absorption line study of the physical and chemical properties of the Leo HI Ring and the Leo I Group as traced by 11 quasar sightlines spread over a 600 kpc X 800 kpc…
