Notes. The mean changes in total subhalo mass (msub), stellar mass (mstell), and gas mass (mgas) for central and satellite galaxies around the time of infall are shown. The mass changes are computed over two six-snapshot windows (∼0.5 Gyr each) for the two most massive samples used in this work: one between the time of infall and ∼0.5 Gyr before infall, and another between ∼0.5 and ∼1 Gyr before infall. A positive value indicates that the corresponding property increases towards infall.
