Centre of Expertise — Neutrinos & Cosmic rays
The centre aims at providing expertise on low- to high and ultra-high energy neutrino astronomy within the context of MM astronomy. The centre includes experts distributed across several institutes of CNRS as well as UCLouvain, USC, BUW, GSSI which provide complementary expertise. The experts are involved in ANTARES, KM3NeT, and IceCube. They are working on point sources with steady, flaring or transient emission profiles, which allow the centre to provide an extensive expertise on neutrino searches from a large variety of astrophysical sources. USC and BUW are involved in the Pierre Auger Observatory and provide expertise on searching for diffuse and point-source fluxes from very high energy sources.
The centre will provide dedicated expert support on:
- Real-time and offline neutrino event selections in ANTARES, KM3NeT, and IceCube
- Data analysis framework for neutrino searches from a large variety of astrophysical sources
- Joint neutrino and MM analyses
- High-energy neutrino diffuse emissions
