Unveiling the high-energy neutrino sky

High-energy neutrinos can propagate over cosmological distances unabated by intervening matter and radiation fields, carrying with them information about some of the most powerful objects in the Universe. At MeV energies, two astrophysical neutrino sources have been detected so far: the Sun and supernova 1987A. At higher energies, neutrinos are expected to be produced in hadronic interactions of cosmic rays with ambient matter or radiation fields near their source or during propagation. Pinpointing the source of these neutrinos can therefore reveal the location of the astrophysical accelerators responsible for the cosmic ray flux. The discovery of an astrophysical flux of high-energy neutrinos by IceCube in 2013, followed by the identification of a blazar as a potential neutrino source in 2017, are major steps forward in this search. This talk will present an overview of the current status of high-energy neutrino astronomy and provide an outlook for the future of the field.
