Fraction of the (z = 0) in situ stellar mass of galaxies brought in by distinct accretion channels (left panel). We define fresh accretion as gas acquired from the IGM that has remained in the halo since it first entered (orange). Gas that was recycled between the galaxy and the halo by feedback processes is labeled wind recycled (green). Deposition of gas by satellites directly into the gaseous disks of centrals (≤2 R_SF, 1/2; red) is further contrasted against the stripping of gas at farther distances (brown). Lastly, gas that is ejected or stripped from other halos, i.e., not satellites, is shown in purple. Colored diamonds show analogous measurements from the FIRE cosmological simulations (Anglés-Alcázar et al. 2017). Both the bars and the diamonds show stacked values. For comparison, the middle and right plots show the same categories for ex situ stars and dark matter particles, respectively.
