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…
