Calculation of the local density of relic neutrinos

de Salas, P. F., Gariazzo, S., Lesgourgues, J. et al.

Understand

Nonzero neutrino masses are required by the existence of flavour oscillations, with values of the order of at least 50 meV.

We consider the gravitational clustering of relic neutrinos within the Milky Way, and used the $N$-one-body simulation technique to compute their density enhancement factor in the neighbourhood of the Earth with respect to the average cosmic density.
Compared to previous similar studies, we pushed the simulation down to smaller neutrino masses, and included an improved treatment of the baryonic and dark matter distributions in the Milky Way.
Our results are important for future experiments aiming at detecting the cosmic neutrino background, such as the Princeton Tritium Observatory for Light, Early-universe, Massive-neutrino Yield (PTOLEMY) proposal.
