Description
The KM3NeT Collaboration is building two deep-sea Cherenkov neutrino telescopes in the Mediterranean Sea. KM3NeT/ARCA, located off the coast of Sicily, is designed to detect TeV–PeV neutrinos. With an angular resolution lower than 0.1° for muon neutrinos above 300 TeV and an optimal visibility of the Galactic plane and Galactic Centre, KM3NeT/ARCA is particularly well suited to search for cosmic neutrino sources. KM3NeT/ORCA, being built off the coast of Toulon, France, is optimised for the study of neutrinos in the GeV–TeV range, primarily to determine the neutrino mass ordering, while also contributing to astrophysical searches at lower energies and enhancing sensitivity to softer spectra.
In this contribution, results on searches for neutrino point sources are presented. The analyses use a binned likelihood approach and are based on data collected by KM3NeT/ARCA and KM3NeT/ORCA during their construction phases, with evolving detector geometries. Together, these analyses demonstrate KM3NeT’s growing capability to detect and localise neutrino sources across a broad energy range, strengthening its role in the global multi-messenger network.
