Neutrino clustering in the Milky Way
  The Cosmic Neutrino Background is a prediction of the standard cosmological
model, but it has been never observed directly. In the experiments with the aim
of detecting relic CNB neutrinos, currently under development, the expected
event rate depends on the local density of relic neutrinos. Since massive
neutrinos can be attracted by the gravitational potential of our galaxy and
cluster around it, a local overdensity of cosmic neutrinos should exist.
Considering the minimal masses guaranteed by neutrino oscillations, we review
the computation of the local density of relic neutrinos and we present
realistic prospects for a PTOLEMY-like experiment.
