redMaPPer IV: Photometric Membership Identification of Cluster Galaxies with 1% Precision
Eduardo Rozo, Eli S. Rykoff, Matthew Becker +2
In order to study the galaxy population of galaxy clusters with photometric data one must be able to accurately discriminate between cluster members and non-members. The redMaPPer…
Dark Sky Simulations: Early Data Release
Samuel W. Skillman, Michael S. Warren, Matthew J. Turk +3
The Dark Sky Simulations are an ongoing series of cosmological N-body simulations designed to provide a quantitative and accessible model of the evolution of the large-scale Univer…
Combining Dark Energy Survey Science Verification Data with Near Infrared Data from the ESO VISTA Hemisphere Survey
Manda Banerji, S. Jouvel, H. Lin +74
We present the combination of optical data from the Science Verification phase of the Dark Energy Survey (DES) with near infrared data from the ESO VISTA Hemisphere Survey (VHS). T…
Orientation Bias of Optically Selected Galaxy Clusters and Its Impact on Stacked Weak Lensing Analyses
Jörg P. Dietrich, Yuanyuan Zhang, Jeeseon Song +15
Weak-lensing measurements of the averaged shear profiles of galaxy clusters binned by some proxy for cluster mass are commonly converted to cluster mass estimates under the assumpt…
Mass and galaxy distributions of four massive galaxy clusters from Dark Energy Survey Science Verification data
P. Melchior, E. Suchyta, E. Huff +89
We measure the weak-lensing masses and galaxy distributions of four massive galaxy clusters observed during the Science Verification phase of the Dark Energy Survey. This pathfinde…
Formation of disk galaxies in preheated media: a preventative feedback model
Yu Lu, H. J. Mo, Risa H. Wechsler
We introduce a semi-analytic galaxy formation model implementing a self-consistent treatment for the hot halo gas configuration and the assembly of central disks. Using the model,…
