Checking the Dark Matter Origin of a 3.53 keV Line with the Milky Way Center
Checking the Dark Matter Origin of a 3.53 keV Line with the Milky Way Center
We detect a line at 3.539±0.011 keV in the deep exposure data set of the Galactic center region, observed with the x-ray multi-mirror mission Newton. The dark matter interpretation of the signal observed in the Perseus galaxy cluster, the Andromeda galaxy [A. Boyarsky et al., Phys. Rev. Lett. 113, 251301 …
