The Infrared Properties of Hickson Compact Groups
K. E. Johnson, J. E. Hibbard, S. C. Gallagher +4
Compact groups of galaxies provide a unique environment to study the mechanisms by which star formation occurs amid continuous gravitational encounters. We present 2MASS (JHK), Spi…
Probing Quasar Outflows with Intrinsic Narrow Absorption Lines
T. Misawa, M. Eracleous, J. C. Charlton +5
We present statistical and monitoring results of narrow absorption lines that are physically related to quasars (i.e., intrinsic NALs). We use Keck/HIRES spectra of 37 optically br…
Studying the Gaseous Phases of Galaxies with Background QSOs
Jane C. Charlton
High resolution rest frame UV quasar absorption spectra covering low and high ionization species, as well as the Lyman series lines, provide remarkably detailed information about t…
Millions of Single Cloud Weak MgII Systems
Chris Churchill, Jane Rigby, Jane Charlton
We report on a population of absorption systems selected by the presence of very weak Mg II doublets. A sub-population of these systems are iron enriched and have near solar metall…
Phase Structure of Weak MgII Absorbers: Star Forming Pockets Outside of Galaxies
Jane C. Charlton, Christopher W. Churchill, Jie Ding +3
A new and mysterious class of object has been revealed by the detection of numerous weak MgII doublets in quasar absorption line spectra. The properties of these objects will be re…
Mapping Metal-Enriched High Velocity Clouds to Very Low HI Column Densities
Chris Churchill, Jane Charlton, Joe Masiero
Our galaxy is the nearest known quasar absorption line system, and it uniquely provides us with an opportunity to probe multiple lines of sight through the same galaxy. This is ess…
