Simulation of Gravitational Superclustering of Massive Neutrinos

Abstract

Results of a numerical simulation of large-scale, plane, symmetric gravitational clustering of massive neutrinos are presented. It is shown that neutrinos may cluster in galactic halos in the adiabatic scenario of galaxy formation. The population of test particles exhibits very little phase mixing, suggesting that the scale of galactic halos may be set by the neutrino mass.
