Abstract
A bstract Sterile neutrinos with keV-MeV masses and non-zero transition magnetic moments can be probed through low-energy nuclear or electron recoil measurements. Here we determine the sensitivities of current and future searches, showing how they can probe a previously unexplored parameter region. Future coherent elastic neutrino-nucleus scattering (CE ν NS) or elastic neutrino-electron scattering (E ν ES) experiments using a monochromatic 51 Cr source can fully probe the region indicated by the recent XENON1T excess.
