Total cold gas mass, M_cg, (in M_⊙) vs. number of satellite galaxies per halo (N_sats) for CGM+Satellites (top panels) and CGM-Satellites (bottom panels) for the log M_*C = 10.160–10.405 (left panels), log M_*C = 10.453–10.715 (middle panels), and log M_*C = 10.931–11.288 (right panels) bin halos. Halos belonging to the 25th (plus symbols), interquartile (star symbols), and 75th (filled circles) quartiles are shown for each bin. Respective median values with 1σ ranges (colored cross symbols) are shown for each quartile. In all three mass bins, when including gas associated with satellite galaxies (top panels), there is more M_cg in satellite-rich systems than in satellite-poor systems.
