In this seminar I will extend the properties of the cosmic neutrino background to the non-linear regime. By means of state-of-the-art N-body hydrodynamic simulations, I will investigate the neutrino dynamics down to small scales and redshifts that are not probed by linear theory In particular, I will discuss how the following neutrino properties: the density profile of the neutrino haloes around collapsed objects, the matter clustering as a function of neutrino mass, the neutrino peculiar velocity field and the dark matter halo mass function. These results could be particularly relevant in view of future lensing/clustering experiments like the Euclid satellite, that are expected to measure the total neutrino mass with an error below 30 meV.
