Group infall of different accretion events, depicted as the radial distance of the satellites against time. The R₂₀₀ of the central MW-like galaxy is marked in thick red. The different group infall events are represented with different colours, with the orbits of the primary satellites in thicker solid lines and their smaller companions in thinner transparent lines. The identification time of the group and the R₂₀₀ of the primary satellite are marked in black. Smaller subhaloes within the R₂₀₀ of the primary satellite at this time are considered companions. These accretion events are selected as analogues to events in the MW, as described in Sect. 3.
