The origin of high-energy astrophysical neutrinos: new results and prospects

Abstract

High-energy neutrino astrophysics is rapidly developing, and in the last two years, new and exciting results have been obtained. Among them are the confirmation of the existence of the diffuse astrophysical neutrino flux by the new independent Baikal-GVD experiment, the discovery of the neutrino emission of our Galaxy, new confirmations of the origin of a part of astrophysical neutrinos in blazars, and much more. This brief review, based on the author's presentation at the session of the RAS Physical Science Division "Gamma quanta and neutrinos from space: what we can see now and what we need to see more", summarizes the results obtained since the publication of the review arXiv:2112.09611, and can be considered as a companion to it.
