Relation between ICL and DM radial profiles. Top: ratio between the ICL and DM density profiles. In the left panel, solid lines are the median values, green for GADGET-X and magenta for GIZMO-SIMBA, while the shaded regions are the 16th–84th percentiles. The middle and right panels show the best fit to an exponential curve of the GADGET-X and GIZMO-SIMBA ratios, respectively (the fainter grey lines are for the opposite simulation, for easier comparison between them). The dashed lines depict the best fit (the analytical formula can be seen in the legend), while the dotted lines indicate the 1σ errors. Bottom: same as the top row but for the ratio between ICL and DM velocity dispersion profiles.
