Description

Neutrino telescopes play a fundamental role in highlighting the hadronic component of cosmic ray accelerators in the Universe. The ANTARES underwater neutrino telescope was operated for more than 15 years in the Mediterranean Sea off shore the coast of Toulon, France. The KM3NeT/ARCA detector, designed for the observation of high energy cosmic neutrinos, is under construction at the KM3NeT site off shore Portapalo di Capo Passero, Sicily, Italy.
In this contribution, the first combined analysis of the full ANTARES dataset and the datasets from the partially completed KM3NeT/ARCA neutrino detector is presented. Point-like and extended sources are tested for neutrino emission. The list of sources includes bright γ-ray emitters, galactic γ-ray sources with hints of hadronic components, extragalactic AGN with high flux observed in radio bands. The diffuse flux search with both detectors is also presented, enhanced by an excellent Galactic centre visibility.
