Radial profiles of stellar surface density for barred (red), short-bar (green), and unbarred (blue) galaxies in TNG50 (shaded areas) and TNG100 (points with error bars) from z = 1 (top row) to z = 0 (bottom row). In each panel, all distributions are rescaled by the median radial stellar surface density of the disk galaxy sample from TNG100. The black horizontal line, which corresponds to 1, represents the median radial stellar surface density profile of the TNG100 disk galaxy sample. Points and lines represent the median values of each distribution, while the error bars and shaded areas show the 16–84th percentiles.
