Sunyaev Zel'dovich Effect Observations of Strong Lensing Galaxy Clusters: Probing the Over-Concentration Problem
Megan B. Gralla, Keren Sharon, Michael D. Gladders +23
We have measured the Sunyaev Zel'dovich (SZ) effect for a sample of ten strong lensing selected galaxy clusters using the Sunyaev Zel'dovich Array (SZA). The SZA is sensitive to st…
Constraining the Redshift Evolution of FIRST Radio Sources in RCS1 Galaxy Clusters
Megan B. Gralla, Michael D. Gladders, H. K. C. Yee +1
We conduct a statistical analysis of the radio source population in galaxy clusters as a function of redshift by matching radio sources from the Faint Images of the Radio Sky at Tw…
The Redshift Distribution of Giant Arcs in the Sloan Giant Arcs Survey
Matthew B. Bayliss, Michael D. Gladders, Masamune Oguri +4
We measure the redshift distribution of a sample of 28 giant arcs discovered as a part of the Sloan Giant Arcs Survey (SGAS). Gemini/GMOS-North spectroscopy provides precise redshi…
The Hubble Space Telescope Cluster Supernova Survey: II. The Type Ia Supernova Rate in High-Redshift Galaxy Clusters
K. Barbary, G. Aldering, R. Amanullah +40
We report a measurement of the Type Ia supernova (SN Ia) rate in galaxy clusters at 0.9 < z < 1.45 from the Hubble Space Telescope (HST) Cluster Supernova Survey. This is the first…
Gemini/GMOS Spectroscopy of 26 Strong Lensing Selected Galaxy Cluster Cores
Matthew B. Bayliss, Joseph F. Hennawi, Michael D. Gladders +4
We present results from a spectroscopic program targeting 26 strong lensing cluster cores that were visually identified in the Sloan Digital Sky Survey (SDSS) and the Second Red-Se…
SPT-CL J0546-5345: A Massive z > 1 Galaxy Cluster Selected Via the Sunyaev-Zel'dovich Effect with the South Pole Telescope
M. Brodwin, J. Ruel, P. A. R. Ade +64
We report the spectroscopic confirmation of SPT-CL J0546-5345 at <z> = 1.067. To date this is the most distant cluster to be spectroscopically confirmed from the 2008 South Pole Te…
X-ray Properties of the First SZE-selected Galaxy Cluster Sample from the South Pole Telescope
K. Andersson, B. A. Benson, P. A. R. Ade +59
We present results of X-ray observations of a sample of 15 clusters selected via their imprint on the cosmic microwave background (CMB) from the thermal Sunyaev-Zel'dovich (SZ) eff…
A bright, spatially extended lensed galaxy at z = 1.7 behind the cluster RCS2 032727-132623
Eva Wuyts, L. Felipe Barrientos, Michael D. Gladders +7
We present the discovery of an extremely bright and extended lensed source from the second Red Sequence Cluster Survey (RCS2). RCSGA 032727-132609 is spectroscopically confirmed as…
Two Lensed z~3 Lyman Break Galaxies Discovered in the SDSS Giant Arcs Survey
Benjamin P. Koester, Michael D. Gladders, Joseph F. Hennawi +5
We report the discovery of two strongly-lensed z ~ 3 Lyman Break Galaxies (LBGs) discovered as u-band dropouts as part of the SDSS Giant Arcs Survey (SGAS). The first, SGAS J122651…
Two Lensed Lyman-alpha Emitting Galaxies at z~5
Matthew B. Bayliss, Eva Wuyts, Keren Sharon +4
We present observations of two strongly lensed Lyman- Emitting (LAE) galaxies that were discovered in the Sloan Giant Arcs Survey (SGAS). We identify the two sources as…
Optical Redshift and Richness Estimates for Galaxy Clusters Selected with the Sunyaev-Zel'dovich Effect from 2008 South Pole Telescope Observations
F. W. High, B. Stalder, J. Song +68
We present redshifts and optical richness properties of 21 galaxy clusters uniformly selected by their Sunyaev-Zel'dovich signature. These clusters, plus an additional, unconfirmed…
Galaxy Clusters Selected with the Sunyaev-Zel'dovich Effect from 2008 South Pole Telescope Observations
K. Vanderlinde, T. M. Crawford, T. de Haan +56
We present a detection-significance-limited catalog of 21 Sunyaev-Zel'dovich selected galaxy clusters. These clusters, along with 1 unconfirmed candidate, were identified in 178 de…
