Supernova Neutrinos

Neutrinos are key players in core-collapse supernovae, which are the catastrophic explosions of massive stars. They are also important messengers to probe unknown physical properties related to the astrophysical events, the fundamental properties of neutrinos, and certain physics candidates beyond the Standard Model of particle physics. In this talk, I'll introduce the mechanism of neutrino emission from core-collapse supernovae, and discuss some lessons that we have learned from SN1987a as well as what we expect to learn from the next galactic supernova. I'll also talk about our recent efforts in understanding the elusive phenomenon of neutrino flavor oscillations in supernovae, which is a central missing piece of current theoretical modeling of supernova explosion.
