Abstract: The existence of neutrino masses and dark matter calls for new physics beyond the standard model. In the new physics models, one may encounter secret interactions among neutrinos themselves, which have hardly been tested in terrestrial experiments. In this talk, we show that the core-collapse supernovae and the early Universe, where neutrinos can be in thermal equilibrium with background particles, can serve as unique laboratories to constrain secret neutrino interactions.
