Description
KM3NeT is a multi-site telescope designed to detect and study cosmic neutrinos and their origin, as well as to improve the knowledge of the intrinsic neutrino properties. Composed of two underwater Cherenkov neutrino telescopes located at two deep-sea sites in the Mediterranean, the KM3NeT infrastructure includes KM3NeT-ARCA (Astrophysics Research with Cosmics in the Abyss), offshore Portopalo di Capo Passero (Sicily, Italy), dedicated to the analysis of high-energy astrophysical neutrinos, from hundreds of GeV up to hundreds of PeV, and KM3NeT-ORCA (Oscillation Research with Cosmics in the Abyss), offshore Toulon (France), designed to investigate neutrino oscillation and mass hierarchy through the detection of atmospheric neutrinos from hundreds of MeV up to the TeV scale.
Despite being in a partial configuration, the KM3NeT- ARCA telescope has already yielded groundbreaking results, including the detection of the first ultra-high-energy astrophysical neutrino, KM3-230213A. This significant observation highlights the remarkable capabilities of deep-sea neutrino telescopes and underscores their potential to uncover novel high-energy astrophysical phenomena. This contribution will review the key results already achieved with KM3NeT-ARCA in the field of neutrino astrophysics, underlining the importance of having the KM3NeT detector in the future multi-messenger panorama.
