Search for a photon peak from keV-scale dark matter annihilation with NuSTAR: Constraints on after 11 years of observations
E. I. Zakharov, V. V. Barinov, D. S. Gorbunov +2
We report new constraints on the velocity-independent annihilation cross section of keV-scale dark matter particles based on 11 years of observations with the…

Strong limits on keV-scale galactic sterile neutrino dark matter with stray light from NuSTAR after 11 years of operation
R. A. Krivonos, V. V. Barinov, A. A. Mukhin +1
Using tremendous photon statistics gained with the stray light aperture of the NuSTAR telescope over 11 years of operation, we set strong limits on the emission of close to monochr…

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…
