Institutions participating to KM3NeT4RR Project

Lead Applicant

KM3NeT4RR is going to be a unique highly advanced underwater observatory in the northern hemisphere that will complement the scientific activities of the IceCube detector by capturing neutrinos coming from the southern hemisphere.

neutrino astronomy

with an superior angular resolution, it will allow to identify the sources of cosmic neutrinos, as well as to measure the energy spectra and flavour composition of the fluxes;

marine sciences

large opportunities for sensor connection providing long-term, high-bandwidth, continuous data collection.
Moreover, these data can be correlated with the data from the neutrino detector itself, which can also monitor bioluminescent and bioacoustics activities and sea currents

About

A new observational window on the Universe

The project is expected to generate a wealth of scientific, economical and social effects. From a scientific point of view, the KM3NeT4RR data will allow opening a new observational window on the Universe, searching for answers to some of the most fundamental and yet unsolved astrophysical problems, such as the origin and the mechanisms of production of cosmic rays, the physical processes at the origin of the very powerful “gamma-ray bursts” or the nature of dark matter. A well-founded hypothesis connects dark matter to the existence of Weak Interacting Massive Particles predicted by some of the most advanced particle physics theories. The detection of anomalous neutrino fluxes emitted by gravitational attractors such as the Sun and the Galactic center would provide indirect evidence of this fundamental theory. The KM3NeT telescope allows the validation of this hypothesis, contributing to the solution of a challenging scientific problem.

Project work ….

With the aim to reinforce the existing infrastructure to reach the goal of having competitive scientific results in the field of astroparticle physics and multi-messenger astronomy the project has been organized in working packages (WPs). More Info
