Determining the Halo Mass Scale where Galaxies Lose Their Gas
Gregory Rudnick, Pascale Jablonka, John Moustakas +9
A major question in galaxy formation is how the gas supply that fuels activity in galaxies is modulated by their environment. We use spectroscopy of a set of well characterized clu…
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…
The mass profile and dynamical status of the z~0.8 galaxy cluster LCDCS 0504
L. Guennou, A. Biviano, C. Adami +34
Constraints on the mass distribution in high-redshift clusters of galaxies are not currently very strong. We aim to constrain the mass profile, M(r), and dynamical status of the $z…
Structure and substructure analysis of DAFT/FADA galaxy clusters in the [0.4-0.9] redshift range
L. Guennou, C. Adami, F. Durret +29
We analyse the structures of all the clusters in the DAFT/FADA survey for which XMM-Newton and/or a sufficient number of galaxy redshifts in the cluster range is available, with th…
The Type II Supernova Rate in z~0.1 Galaxy Clusters from the Multi-Epoch Nearby Cluster Survey
M. L. Graham, D. J. Sand, C. J. Bildfell +7
We present 7 spectroscopically confirmed Type II cluster supernovae (SNeII) discovered in the Multi-Epoch Nearby Cluster Survey, a supernova survey targeting 57 low redshift 0.05 <…
PHL 1811 Analogs: A Population of X-ray Weak Quasars
Jianfeng Wu, W. N. Brandt, Patrick B. Hall +6
We report on a population of X-ray weak quasars with similar UV emission-line properties to those of the remarkable quasar PHL 1811. All radio-quiet PHL 1811 analogs are notably X-…
Detection of Outflowing and Extraplanar Gas in Disks in an Assembling Galaxy Cluster at z=0.37
E. Freeland, K-V. Tran, T. Irwin +5
We detect ionized gas characteristics indicative of winds in three disk-dominated galaxies that are members of a super-group at z=0.37 that will merge to form a Coma-mass cluster.…
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
David J. Sand, Melissa L. Graham, Chris Bildfell +8
We describe the Multi-Epoch Nearby Cluster Survey (MENeaCS), designed to measure the cluster Type Ia supernova (SN Ia) rate in a sample of 57 X-ray selected galaxy clusters, with r…
Intracluster light in clusters of galaxies at redshifts 0.4<z<0.8
L. Guennou, C. Adami, C. Da Rocha +27
The study of intracluster light can help us to understand the mechanisms taking place in galaxy clusters, and to place constraints on the cluster formation history and physical pro…
A Search for Young Stars in the S0 Galaxies of a Super-Group at z=0.37
Dennis W. Just, Dennis Zaritsky, Kim-Vy H. Tran +3
We analyze GALEX UV data for a system of four gravitationally-bound groups at z=0.37, SG1120, which is destined to merge into a Coma-mass cluster by z=0, to study how galaxy proper…
A Population of X-ray Weak Quasars: PHL 1811 Analogs at High Redshift
Jianfeng Wu, W. N. Brandt, Patrick B. Hall +6
We report the results from Chandra and XMM-Newton observations of a sample of 10 type 1 quasars selected to have unusual UV emission-line properties (weak and blueshifted high-ioni…
Intracluster supernovae in the Multi-epoch Nearby Cluster Survey
D. J. Sand, M. L. Graham, C. Bildfell +7
The Multi-Epoch Nearby Cluster Survey (MENeaCS) has discovered twenty-three cluster Type Ia supernovae (SNe) in the 58 X-ray selected galaxy clusters (0.05 < z < 0.15) surveyed. Fo…
LBT/LUCIFER Observations of the z~2 Lensed Galaxy J0900+2234
Fuyan Bian, Xiaohui Fan, Jill Bechtold +11
We present rest-frame optical images and spectra of the gravitationally lensed, star-forming galaxy J0900+2234 (z=2.03). The observations were performed with the newly commissioned…
The Environmental Dependence of the Evolving S0 Fraction
Dennis W. Just, Dennis Zaritsky, David J. Sand +2
We reinvestigate the dramatic rise in the S0 fraction, f_S0, within clusters since z ~ 0.5. In particular, we focus on the role of the global galaxy environment on f_S0 by compilin…
The X-ray Properties of the Most-Luminous Quasars from the Sloan Digital Sky Survey
D. W. Just, W. N. Brandt, O. Shemmer +4
Utilizing 21 new Chandra observations as well as archival Chandra, ROSAT, and XMM-Newton data, we study the X-ray properties of a representative sample of 59 of the most optically…
