Gas density of the same subhalo across the different models during their infall to the host halo. Gas density is weighted by itself to emphasize the dense regions. Each column represents a different model, while each row indicates the same infall stage. These stages are highlighted in Figure 10: (a) first snapshot at a distance to the host lower than $2R_{\mathrm{vir}}^{\mathrm{host}}$, (b) at t_infall, (c) during the first apocenter, and (d) during the second infall, slightly before the second pericenter. White solid circle show the subhalo virial radius, while the white arrow provides information about the subhalo's velocity, showing the predicted position of the center of the subhalo in 100 Myr assuming the same velocity as in the current snapshot. An animation showcasing the complete temporal evolution of the subhalo's gas density and temperature during the infall is available online (see footnote ⁴).
