The redshift dependence of the structure of massive Λ cold dark matter haloes
The redshift dependence of the structure of massive Λ cold dark matter haloes
(Abridged) We use two very large cosmological simulations to study how the density profiles of relaxed LCDM dark halos depend on redshift and on halo mass. We confirm that these profiles deviate slightly but systematically from the NFW form and are better approximated by the empirical formula, $d\log ρ/d\log r …
