Dark matter density profiles at z = 0 when considering five halo mass bins (left to right). We calculated the mean dark matter profile in bins of Δlog(M_vir) = 0.2 dex around the mean value, both in the FP (solid) and dark (dashed) runs. The profiles were calculated in logarithmically spaced spherical shells from 1 kpc to the halo virial radius. In order to capture both good statistics at high masses and the highest resolution, we average profiles from both the 50/A and 100/A runs for all models – except WDM1, where 50/B is employed. The small panels show (i) the ratio of each mean profile to its dark counterpart and (ii) to the CDM version. We observe an opposite trend in mass in the WDM and SIDM models. The latter creates larger density cores at high masses and cuspy profiles at M_vir≤10¹² M_⊙, while the former lowers the central density at low masses (halo masses below the half-mode mass M_hm). In all panels, the grey bands indicate 2.3ϵ_DM for both runs, which is often used as the minimum distance for reliable measurements.
