Abstract: The origin of the dark matter of the Universe and the mechanism generating light neutrino masses could be tightly linked. In this talk, based on arXiv:2308.01341, we consider the possibility to simultaneously explain oscillation data and dark matter in the form of a keV-sterile neutrino. We thoroughly study the DM production through freeze-in two-body decays, accounting for thermal effects modifying the neutrino mixing and thus the production rates. Our study shows that the freeze-in dark matter production can be efficient and thus further study is necessary to identify interesting regions of parameter space that simultaneously account for DM and neutrino masses.
