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
