Explore neutrino physics beyond the Standard Model in this 44-minute conference talk from the Interdisciplinary Developments in Neutrino Physics Conference. Delve into topics such as the neutrino portal, reactor neutrino fluxes, the Gallium anomaly, sterile neutrinos, and neutrino magnetic moments. Examine terrestrial constraints, new neutrino interactions, and anomalous neutral and charged currents in oscillations. Investigate the implications for stellar cooling and gain insights into the latest developments in neutrino phenomenology.
