| الوصف: | 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 monochromatic photons from the radiative decays of putative dark matter sterile neutrinos in the Milky Way. In the energy range of 3-20 keV covered by the NuSTAR, the obtained limits reach the edge of theoretical predictions of realistic models leaving only a small room left to explore. Comment: 11 pages, 11 figures, submitted to Phys. Rev. Lett.; Comments and suggestions are welcome |
