Visualisation of the dark matter (top), gas (middle), and stellar (bottom) projected mass distributions in a Milky-Way mass halo (Mvir = 6.9×1012 M⊙ in CDM at z = 0) from the 100/A runs. From left to right, CDM, SIDM1, vSIDM, and WDM3. We zoom-in to the central parts of the halo, ∼0.5 rvir in the top and middle panels, and ∼0.25 rvir in the stellar distribution. In the latter, we also mark the distance corresponding to twice the stellar half-mass radius. One can observe a decrease in the number of substructures in WDM3 as well as a clear difference in the gas dynamics and the shape of the stellar distribution.
