AstroNu

The AstroNu team aims at unveiling the nature of fascinating weakly interacting elementary particles, such as the neutrino, and explores the role of these  particles in astrophysical sources, in the synthesis of new elements, and in the Early Universe. The AstroNu group also adopts neutrinos as probes of the inner workings of astrophysical transients together with photons, cosmic rays, and gravitational waves.
