The XMM Cluster Survey: Exploring scaling relations and completeness of the Dark Energy Survey Year 3 redMaPPer cluster catalogue
E. W. Upsdell, P. A. Giles, A. K. Romer +67
We cross-match and compare characteristics of galaxy clusters identified in observations from two sky surveys using two completely different techniques. One sample is optically sel…
The XMM Cluster Survey analysis of the SDSS DR8 redMaPPer Catalogue: Implications for scatter, selection bias, and isotropy in cluster scaling relations
P. A. Giles, A. K. Romer, R. Wilkinson +21
In this paper we present the X-ray analysis of SDSS DR8 redMaPPer (SDSSRM) clusters using data products from the Cluster Survey (XCS). In total, 1189 SDSSRM clusters fall wit…
Velocity Dispersions of Clusters in the Dark Energy Survey Y3 redMaPPer Catalog
V. Wetzell, T. E. Jeltema, B. Hegland +96
We measure the velocity dispersions of clusters of galaxies selected by the redMaPPer algorithm in the first three years of data from the Dark Energy Survey (DES), allowing us to p…
The XMM Cluster Survey: new evidence for the 3.5 keV feature in clusters is inconsistent with a dark matter origin
S. Bhargava, P. A. Giles, A. K. Romer +14
There have been several reports of a detection of an unexplained excess of X-ray emission at 3.5 keV in astrophysical systems. One interpretation of this excess is the dec…
Dark Energy Survey Year 1 Results: Cosmological Constraints from Cluster Abundances and Weak Lensing
DES Collaboration, Tim Abbott, Michel Aguena +129
We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear…
Mass Variance from Archival X-ray Properties of Dark Energy Survey Year-1 Galaxy Clusters
A. Farahi, X. Chen, A. E. Evrard +76
Using archival X-ray observations and a log-normal population model, we estimate constraints on the intrinsic scatter in halo mass at fixed optical richness for a galaxy cluster sa…
Stellar mass as a galaxy cluster mass proxy: application to the Dark Energy Survey redMaPPer clusters
A. Palmese, J. Annis, J. Burgad +82
We introduce a galaxy cluster mass observable, , based on the stellar masses of cluster members, and we present results for the Dark Energy Survey (DES) Year 1 observation…
Dark Energy Survey Year 1 Results: Calibration of Cluster Mis-centering in the redMaPPer Catalogs
Y. Zhang, T. Jeltema, D. L. Hollowood +83
The center determination of a galaxy cluster from an optical cluster finding algorithm can be offset from theoretical prescriptions or -body definitions of its host halo center.…
Chandra Follow-Up of the SDSS DR8 redMaPPer Catalog Using the MATCha Pipeline
Devon L. Hollowood, Tesla Jeltema, Xinyi Chen +15
In order to place constraints on cosmology through optical surveys of galaxy clusters, one must first understand the properties of those clusters. To this end, we introduce the Mas…
Dark Energy Survey Year 1 Results: Weak Lensing Mass Calibration of redMaPPer Galaxy Clusters
T. McClintock, T. N. Varga, D. Gruen +99
We constrain the mass--richness scaling relation of redMaPPer galaxy clusters identified in the Dark Energy Survey Year 1 data using weak gravitational lensing. We split clusters i…
Galaxies in X-ray Selected Clusters and Groups in Dark Energy Survey Data II: Hierarchical Bayesian Modeling of the Red-Sequence Galaxy Luminosity Function
Y. Zhang, C. J. Miller, P. Rooney +77
Using X-ray selected clusters in the Dark Energy Survey Science Verification data, we constrain the luminosity function (LF) of cluster red sequence galaxies as a functi…
Weak-lensing mass calibration of redMaPPer galaxy clusters in Dark Energy Survey Science Verification data
P. Melchior, D. Gruen, T. McClintock +78
We use weak-lensing shear measurements to determine the mean mass of optically selected galaxy clusters in Dark Energy Survey Science Verification data. In a blinded analysis, we s…
The XMM Cluster Survey: evolution of the velocity dispersion -- temperature relation over half a Hubble time
Susan Wilson, Matt Hilton, Philip J. Rooney +26
We measure the evolution of the velocity dispersion--temperature (--) relation up to using a sample of 38 galaxy clusters drawn from the \textit{XMM}…
