Evolution of the total density profile over 12 Gyr in simulations S1 (left) and S2 (right). The symbols have the same meaning as in Fig. 2. The red and yellow dashed lines mark the initial profiles (models M1 and M2). The gray shaded area is the present-day total density profile of the Fornax dSph estimated by Pascale et al. (2018) with its 1-σ uncertainty. The hatched parts of the graphs indicate regions where the total mass distribution of the Fornax dSph is poorly constrained, because there are no luminous tracers of the gravitational potential.
