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