Why we need MeV observations - a neutrino perspective

Prof. Naoko Neilsen

IceCube is a high-energy neutrino observatory that aims to resolve sources of astrophysical neutrinos. Most of the source search analyses in IceCube rely extensively on gamma-ray observations, and particularly on Fermi observations because of the full-sky nature of the instrument. Despite our numerous searches correlating the GeV gamma ray band and the TeV neutirno band, no discoveries have been made to date, except for one strong evidence of a possible correlation. This talk will cover what the experimental neutrino astrophysics community wishes for in an MeV instrument, and why it is crucial to have MeV observations for the future of neutrino astrophysics.
