Tidal radius and its enclosed mass as a function of time. For the satellite halo, evolved with different DM models, the tidal radius (solid lines) according to Eq. (E.1) and the mass within it (dashed lines) are shown. All simulations shown here share a resolution of N = 10⁷ particles and a gravitational softening length of ϵ = 1.0 kpc. Further information on the simulations T, W, X, Y, and Z is provided in Table A.1.
