Scientific paper

I apply the modified spherical infall model to test the dependence of the
shape of density profiles of dark matter halos on redshift. The model predicts
that the density profile of a halo of a given mass steepens with time and its
concentration parameter changes like c~1/(1+z_0)^2.
