H-based Star Formation Rates in and around z 0.5 EDisCS clusters
Jennifer R. Cooper, Gregory H. Rudnick, Gabriel G. Brammer +14
We investigate the role of environment on star-formation rates of galaxies at various cosmic densities in well-studied clusters. We present the star-forming main sequence for 163 g…
SEEDisCS II. Molecular gas in galaxy clusters and their large scale structure: low gas fraction galaxies, the case of CL1301.71139
D. Spérone-Longin, P. Jablonka, F. Combes +8
This paper is the second of a series that tackles the properties of molecular gas in galaxies residing in clusters and their related large-scale structures. Out of 21 targeted fiel…
The Ultraviolet and Infrared Star Formation Rates of Compact Group Galaxies: An Expanded Sample
Laura Lenkic, Panayiotis Tzanavaris, Sarah Gallagher +8
Compact groups of galaxies provide insight into the role of low-mass, dense environments in galaxy evolution because the low velocity dispersions and close proximity of galaxy memb…
Exploring X-ray Binary Populations in Compact Group Galaxies with
P. Tzanavaris, A. E. Hornschemeier, S. C. Gallagher +5
We obtain total galaxy X-ray luminosities, , originating from individually detected point sources in a sample of 47 galaxies in 15 compact groups of galaxies (CGs). For the gr…
Global Properties of Neutral Hydrogen in Compact Groups
Lisa May Walker, Kelsey E. Johnson, Sarah C. Gallagher +5
Compact groups of galaxies provide a unique environment to study the evolution of galaxies amid frequent gravitational encounters. These nearby groups have conditions similar to th…
Preprocessing Among the Infalling Galaxy Population of EDisCS Clusters
Dennis W. Just, Matthew Kirby, Dennis Zaritsky +15
We present results from a low-resolution spectroscopic survey for 21 galaxy clusters at selected from the ESO Distant Cluster Survey. We measured spectra using the…
Reverberation Mapping of the Kepler-Field AGN KA1858+4850
Liuyi Pei, Aaron J. Barth, Greg S. Aldering +40
KA1858+4850 is a narrow-line Seyfert 1 galaxy at redshift 0.078 and is among the brightest active galaxies monitored by the Kepler mission. We have carried out a reverberation mapp…
Some Like It Hot: Linking Diffuse X-ray Luminosity, Baryonic Mass, and Star Formation Rate in Compact Groups of Galaxies
Tyler D. Desjardins, Sarah C. Gallagher, Ann E. Hornschemeier +6
We present an analysis of the diffuse X-ray emission in 19 compact groups of galaxies (CGs) observed with Chandra. The hottest, most X-ray luminous CGs agree well with the galaxy c…
A View of Point Sources in Hickson Compact Groups: High AGN fraction but a dearth of strong AGNs
P. Tzanavaris, S. C. Gallagher, A. E. Hornschemeier +6
We present X-ray point source catalogs for 9 Hickson Compact Groups (HCGs, 37 galaxies) at distances Mpc. We perform detailed X-ray point source detection and p…
Stellar Populations in Compact Galaxy Groups: a Multi-Wavelength Study of HCGs 16, 22, and 42, their Star Clusters and Dwarf Galaxies
I. S. Konstantopoulos, A. Maybhate, J. C. Charlton +10
We present a multi-wavelength analysis of three compact galaxy groups, HCGs 16, 22, and 42, which describe a sequence in terms of gas richness, from space- (Swift, HST, Spitzer) an…
Spectroscopic Observations of SN 2012fr: A Luminous Normal Type Ia Supernova with Early High Velocity Features and Late Velocity Plateau
M. J. Childress, R. A. Scalzo, S. A. Sim +55
We present 65 optical spectra of the Type Ia supernova SN 2012fr, of which 33 were obtained before maximum light. At early times SN 2012fr shows clear evidence of a high-velocity f…
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…
