Neutrino telescopes offer unique insights into some of the most extreme and energetic phenomena in the Universe. The ANTARES detector, which operated for 16 years off the coast of Toulon (France) until 2022, has played a pioneering role in deep-sea neutrino observations. The next-generation KM3NeT neutrino telescopes, ORCA and ARCA, designed to push the boundaries of atmospheric and astrophysical neutrino detection, are currently under construction.
In recent years, the search for astrophysical neutrino sources has gained momentum, as their detection would provide crucial evidence of hadronic acceleration mechanisms at play in the most powerful cosmic environments. This study analyses the combined dataset from ANTARES and the available KM3NeT/ARCA observations, focusing on the detection of high-energy neutrinos from point-like sources.
A comprehensive catalog of about 100 point-like sources and the ones with extensions up to few degrees has been examined for potential neutrino emissions. This selection includes prominent gamma-ray emitters, Galactic gamma-ray sources with possible hadronic components (TeVCat), extragalactic AGNs with intense radio flux detected by VLBI, and the most promising candidates previously investigated by IceCube and ANTARES. The results of this analysis represent a significant step toward uncovering the origin of cosmic neutrinos and advancing multi-messenger astronomy.
