Neutrino Astronomy with future neutrino telescopes

Plenary Talk presented at the XX International Workshop on Neutrino Telescopes - Venice 23-27 October 2023

Abstract:

In the past decade, IceCube has established cosmic neutrino flux. IceCube has also observed neutrinos from the first extragalactic sources and the Milky Way. These observations set the stage for the next generations of neutrino telescopes worldwide. Multiple large water Cherenkov telescopes of kilometer-scale are being constructed or developed. Even more ambitious telescopes are being proposed and developed at the ten km scale. Multiple initiatives at the 1000km^3 target scale are proposed using radio and Earth-skimming nu_tau approaches at higher energies. I will review the current and future detectors. An order-of-magnitude increase within the next decade is realistic and urgently needed to obtain more sky coverage and increase the sensitivity by order of magnitude.
