摘要：

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 surveys. These constraints are derived from observations of the Milky Way Halo, 33 Local Group spheroidal dwarf (dSph) galaxies and separately for the dSph galaxy Ursa Major III/UNIONS 1. The constraints from the Milky Way Halo are the strongest among others and among all available in literature for this class of dark matter models with particle masses from 4 to 15 keV.
