Abstract: It has been found that the phase space of dark matter particles assembling a galactic halo in cosmological N -body simulations well defines the fine grained structure. Recently accreted particles form distinctive velocity streams with high density contrast. For a fixed observer position, these streams lead to peaks in the velocity distribution. Overall structure is close to that emerging in the secondary infall model.
