The Dark Energy Camera (DECam)
K. Honscheid, D. L. DePoy
In this paper we describe the Dark Energy Camera (DECam), which will be the primary instrument used in the Dark Energy Survey. DECam will be a 3 sq. deg. mosaic camera mounted at t…
Spectroscopic Confirmation of a Massive Red-Sequence-Selected Galaxy Cluster at z = 1.34 in the SpARCS-South Cluster Survey
Gillian Wilson, Adam Muzzin, H. K. C. Yee +10
The Spitzer Adaptation of the Red-sequence Cluster Survey (SpARCS) is a z'-passband imaging survey, consisting of deep (z' ~ 24 AB) observations made from both hemispheres using th…
Spectroscopic Confirmation of Two Massive Red-Sequence-Selected Galaxy Clusters at z ~ 1.2 in the SpARCS-North Cluster Survey
Adam Muzzin, Gillian Wilson, H. K. C. Yee +10
The Spitzer Adaptation of the Red-sequence Cluster Survey (SpARCS) is a deep z'-band imaging survey covering the Spitzer SWIRE Legacy fields designed to create the first large homo…
Pair Analysis of Field Galaxies from the Red-Sequence Cluster Survey
B. C. Hsieh, H. K. C. Yee, H. Lin +2
We study the evolution of the number of close companions of similar luminosities per galaxy (Nc) by choosing a volume-limited subset of the photometric redshift catalog from the Re…
A z=0.9 supercluster of X-ray luminous, optically-selected, massive galaxy clusters
David G. Gilbank, H. K. C. Yee, E. Ellingson +4
We report the discovery of a compact supercluster structure at z=0.9. The structure comprises three optically-selected clusters, all of which are detected in X-rays and spectroscop…
Galaxy Clusters in the Line of Sight to Background Quasars: I. Survey Design and Incidence of MgII Absorbers at Cluster Redshifts
S. Lopez, L. F. Barrientos, P. Lira +7
We describe the first optical survey of absorption systems associated with galaxy clusters at z= 0.3-0.9. We have cross-correlated SDSS DR3 quasars with high-redshift cluster/group…
