Constraints on the parameters of keV-scale mass annihilating Dark Matter obtained with SRG/ART-XC observations
E. I. Zakharov, V. V. Barinov, R. A. Burenin +2
In this paper we present new constraints on the velocity-independent cross section of keV-scale mass annihilating Dark Matter particles obtained with SRG/ART-XC after 4 full-sky su…
