Comparison of the effective radii for our sample of simulated TSA galaxies to effective radii of galaxies from the Siena Galaxy Atlas 2020 (Moustakas et al. 2023). The three different panels correspond to different bins in g − z colour, and each symbol represents the median effective radius in a bin in z-band absolute magnitude of width ΔM_z = 0.2. Measurements in the g-, r-, and z-bands are indicated by different symbols, as indicated in the top panel. The symbols for the SGA-2020 are plotted slightly offset for the sake of clarity.
