Query: Density profiles and clustering of dark halos and clusters of galaxies   Density profiles of cosmological virialized systems, or dark halos, have
recently attracted much attention. I first present a brief historical review of
numerical simulations to quantify the halo density profiles. Then I describe
the latest results on the universal density profile and their observational
confrontation. Finally I discuss a clustering model of those halos with
particular emphasis on the cosmological light-cone effect.
