The observation of neutrino flavor oscillations provides one of the clearest pieces of evidence for physics beyond the Standard Model (BSM). In recent years, experiments have begun to observe astrophysical neutrino sources and to measure neutrino flavor with high precision, opening the door to probing BSM physics in previously unexplored environments and extending the accessible parameter space. In this talk, we will briefly review the current status of neutrino flavor physics. We will then discuss how the same experiments that contribute to precise measurements of neutrino flavor can also detect astrophysical neutrinos over a wide energy range, from MeV to PeV, providing a powerful tool to search for BSM effects. In particular, we will explore scenarios involving new neutrino interactions, light Majorana masses, and other BSM scenarios, and examine how present and future experiments can test these possibilities.
