Total and stellar mean density profiles in the inner parts of the haloes at z = 0, represented by solid and dashed lines. The mass bins are the same as in Fig. 10, and the bottom panels highlight the effect of alternative models on the total density profiles. Similarly to the dark matter profiles, the total density is affected by core formation in SIDM at the high-mass end, and in WDM at the low-mass end, but the core size and depth are reduced.
