Decaying dark matter: the case for a deep X-ray observation of Draco
Mark R. Lovell, Gianfranco Bertone, Alexey Boyarsky +2
Recent studies of M31, the Galactic centre, and galaxy clusters have made tentative detections of an X-ray line at ~3.5 keV that could be produced by decaying dark matter. We use h…
Comment on the paper "Dark matter searches going bananas: the contribution of Potassium (and Chlorine) to the 3.5 keV line" by T. Jeltema and S. Profumo
A. Boyarsky, J. Franse, D. Iakubovskyi +1
We revisit the X-ray spectrum of the central 14' of the Andromeda galaxy, discussed in our previous work [1402.4119]. Recently in [1408.1699] it was claimed that if one limits the…
Checking the dark matter origin of 3.53 keV line with the Milky Way center
Alexey Boyarsky, Jeroen Franse, Dmytro Iakubovskyi +1
We detect a line at 3.539 +/- 0.011 keV in the deep exposure dataset of the Galactic Center region, observed with the XMM-Newton. The dark matter interpretation of the signal obser…
An unidentified line in X-ray spectra of the Andromeda galaxy and Perseus galaxy cluster
Alexey Boyarsky, Oleg Ruchayskiy, Dmytro Iakubovskyi +1
We report a weak line at 3.52+/-0.02 keV in X-ray spectra of M31 galaxy and the Perseus galaxy cluster observed by MOS and PN cameras of XMM-Newton telescope. This line is not know…
