Description
Binary neutron star mergers and collapsars are potential sources of both high-energy (HE) neutrinos and r-process nuclei. In this talk, I will first discuss the HE neutrinos produced by jet-induced shocks. Then, I will explore the possibility that HE neutrinos can be annihilated with low-energy (LE) neutrinos, either emitted from the accretion disk around a black hole or from the beta decay of newly synthesized heavy nuclei within the same source. We suggest that these effects could be tested through precise measurements of the HE neutrino spectrum and flavor composition. Such measurements could play a unique role in identifying binary neutron star mergers and/or collapsars as sources of HE neutrinos and r-process nuclei.
