Relations between j_CGM and j_Env within 2R_hsm to 100 kpc, for SIMBA and TNG, from top to bottom, respectively. The black line is the relation of SFGs and red line is the relation of QGs in each panel. To show the trend more clearly, we present 1:1 baselines, indicated by the magenta dotted lines. For SFGs and QGs, each sample is plotted with a blue dot and an orange circle, respectively. Each line shows the median values, with errors estimated from the 16^th − 84^th percentile ranges.
