Highlights from the ANTARES neutrino telescope

The ANTARES detector, located offshore the French southern coast at about 2500 m under the sea level, was the first deep sea neutrino telescope. Despite its (relative) small size, ANTARES has provided essential contributions to neutrino particle physics and astrophysics. ANTARES was operating in its full configuration from May 2008 to February 2022. After the stop of data taking, the detector was decommissioned between May and June 2022. The large amount of high quality data and its scientific results has proven the reliability of underwater detection technique of high-energy (HE) neutrinos and has pushed the development of the new generation of seawater neutrino telescopes. Its detection principle is based on the collection of the Cherenkov photons emitted along the path of relativistic particles emerging from neutrino interactions in the vicinity of the telescope, using a lattice of almost 900 optical modules, each hosting a 10" photomultiplier, distributed along 12 flexible strings. All information on the signal - time, position and charge - are transmitted to the onshore control station where the data stream is processed using dedicated trigger algorithms. Technical details on ANTARES can be found in [1]. ANTARES detected neutrinos at different energy ranges, from the tens of GeV (when atmospheric neutrino oscillations can be measured), passing to the TeV-scale (relevant for indirect dark matter searches) up to the multi-TeV energies of cosmic neutrinos. The main background in neutrino telescopes comes from atmospheric muons, which can be easily rejected during physics analysis with a directional cut on reconstructed events. In this contribution a highlight of recent results obtained with the ANTARES detector is given.
