Dark matter produced from neutrinos
  In the presence of interactions between neutrinos and dark matter (DM), DM
can potentially be produced via freeze-in from the neutrino sector. We
investigate the implications of such a scenario for the evolution of both DM
and neutrinos in the early Universe, and show that the future cosmic neutrino
detection experiment PTOLEMY might be sensitive to neutrino signals that
originate from DM annihilation in this model.
