The KM3NeT multi-site detector is designed to detect and study cosmic neutrinos and their sources in the Universe, as well as to improve the measurement of the neutrino properties. The research infrastructure, currently under construction, consists of two underwater Cherenkov neutrino telescopes, ARCA and ORCA, located at two abyssal sites in the Mediterranean Sea.

ARCA aims at instrumenting a 1 km3 volume of water, and ORCA will reach a mass of 7 Mton. They will make an essential contribution to multi-messenger astronomy: the observation of neutrinos coming from astrophysical sources will allow us to understand their properties and internal dynamics. ORCA is optimised to measure neutrino properties, like the oscillation parameters or the mass ordering. While both telescopes are collecting data in a partial configuration, they are producing high-impact physics results.



This colloquium will cover the main physics results already obtained with KM3NeT, including the observation of an Ultra High Energy neutrino of astrophysical origin.
