Abstract

The ANTARES deep sea neutrino telescope, installed at the bottom of the Mediterranean Sea, has been continuously taking data for more than ten years. Thanks to its excellent angular resolution in both the muon channel and the cascade channel (induced by all neutrino flavours), ANTARES offers unprecedented sensitivity for neutrino source searches in the Southern sky in the TeV–PeV energy range. In the search for a potential cosmic diffuse neutrino flux using nine years of ANTARES data a mild excess was seen, consistent with the IceCube discovery. The source of these neutrinos still remains unknown.Recent Gravitational Wave (GW) discoveries and joint efforts with other multi-messenger observatories (gamma-ray, X-ray, optical, radio) can contribute to solving the puzzle of the high energy neutrinos origin and cosmic ray acceleration sites. Antares data has been analysed in order to search a neutrino emission in correspondence of all observed GW events, including recent neutron star – neutron star merger GW170817. Moreover, this year the search for neutrino emission from Fast Radio Bursts with 2013–2017 years data was completed. Merging ANTARES and IceCube data for searches of various sources improves the sensitivity as it is demonstrated for the recent Galactic Plane analysis.
