Intragroup and Galaxy-Linked Diffuse X-ray Emission in Hickson Compact Groups
Tyler D. Desjardins, Sarah C. Gallagher, Panayiotis Tzanavaris +9
Isolated compact groups of galaxies (CGs) present a range of dynamical states, group velocity dispersions, and galaxy morphologies with which to study galaxy evolution, particularl…
Evolution of the Population of Very Strong MgII Absorbers
Paola Rodríguez Hidalgo, Kaylan Wessels, Jane Charlton +4
We present a study of the evolution of several classes of MgII absorbers, and their corresponding FeII absorption, over a large fraction of cosmic history: 2.3 to 8.7 Gyrs from the…
Revealing a Ring-like Cluster Complex in a Tidal Tail of the Starburst Galaxy NGC 2146
A. Adamo, L. J. Smith, J. S. Gallagher +9
We report the discovery of a ring-like cluster complex in the starburst galaxy NGC 2146. The Ruby Ring, so named due to its appearance, shows a clear ring-like distribution of star…
Variability of Mini-BAL and BAL Outflows in Quasars
Paola Rodriguez Hidalgo, Fred Hamann, Michael Eracleous +3
We report the results of several programs to study the variability of high-velocity (up to 0.2c) mini-"broad absorption lines" (mini-BALs) and BALs in quasar spectra, and thus to b…
Gemini Spectroscopic Survey of Young Star Clusters in Merging/Interacting Galaxies. IV. Stephan's Quintet
G. Trancho, I. Konstantopoulos, N. Bastian +4
We present a spectroscopic survey of 21 young massive clusters and complexes and one tidal dwarf galaxy candidate (TDG) in Stephan's Quintet, an interacting compact group of galaxi…
Examining the Role of Environment in a Comprehensive Sample of Compact Groups
Lisa May Walker, Kelsey E. Johnson, Sarah C. Gallagher +2
(Abridged) Compact groups, with their high number densities, small velocity dispersions, and an interstellar medium that has not been fully processed, provide a local analog to con…
