New constraints on sterile neutrino dark matter from NuSTAR M31 observations

New constraints on sterile neutrino dark matter from NuSTAR M31 observations

© 2019 American Physical Society. We use a combined 1.2 Ms of NuSTAR observations of M31 to search for x-ray lines from sterile neutrino dark matter decay. For the first time in a NuSTAR analysis, we consistently take into account the signal contribution from both the focused and unfocused fields of...
