Status and results of the KM3NeT neutrino telescope — •Thomas Eberl for the KM3NET-ERLANGEN collaboration — Erlangen Centre for Astroparticle Physics (ECAP), Friedrich-Alexander-Universität Erlangen-Nürnberg, Nikolaus-Fiebiger-Str. 2, 91058 Erlangen, Germany

KM3NeT is the next-generation underwater Cherenkov neutrino detector operational and under construction in the Mediterranean Sea at two different locations. The ORCA detector, close to Toulon, features a dense configuration of optical modules, optimised for the study of interactions of neutrinos with energies down to a few GeV. The same technology, albeit in a sparser configuration, is used for high-energy (TeV-PeV) neutrino astronomy with the ARCA neutrino telescope off the coast of Sicily. Both instruments are operational, take data since several years, and have been completed to more than 20% of their expected final volume. In this talk the construction plans and status will be reviewed and an overview of recent results on particle physics and neutrino astronomy will be given. The recent discovery of an extreme-energy neutrino will be discussed.
