Astronomy with Neutrino Telescopes

In recent decades, high-energy neutrinos of astrophysical origin have become integral members of the multi-messenger astronomy community. Neutrino telescopes have a very particular way to observe the sky, with characteristics different from any other telescope. They are capable of continuously observing the entire sky simultaneously, yet they also necessitate the accumulation of a significant amount of statistical data. IceCube reported the first evidence of high-energy cosmic neutrinos in 2013, with very interesting excesses in the later years from TXS 0506+056, NGC 1068 and also the Galactic plane. The discovery of new sources holds promise during the current decade, as an increasing number of detectors yield more statistical data with even better angular resolutions.

In this talk, I will discuss the distinctive features of neutrino telescopes and provide an overview of the current state of neutrino astronomy. I will explore various cosmic neutrino search strategies, ranging from diffuse flux investigations to gravitational wave follow-ups, with a focus on Mediterranean-based projects such as ANTARES and KM3NeT, in conjunction with IceCube.
