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…
