Astrophysics Seminar

Neutrinos are elusive and one of the best-kept secrets of our Universe. Other than the mass differences and the mixing angles of the three Standard Model neutrino flavours, we do not know much about them. Naturally, many theoretical models have been proposed over the years that suggest hidden interactions in the neutrino sector, possibly even with dark matter. Some of the models have even claimed to ease the Hubble Tension. In this talk, I will show how non-standard physics in the neutrino sector could show up as observable signatures, and what the latest observations and experiments can tell us about them.
