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…
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…
The Cluster Survey: joint modelling of the scaling relation for clusters and groups of galaxies
Leyla Ebrahimpour, Pedro T. P. Viana, Maria Manolopoulou +16
We characterize the X-ray luminosity--temperature () relation using a sample of 353 clusters and groups of galaxies with temperatures in excess of 1 keV, spanning the…
