Comparison of the best-fit size evolution at a fixed stellar mass of M = 5 × 1010M between this work and previous studies, including A. van der Wel et al. (2014), M. Martorano et al. (2024) (at a similar mass but not exactly), N. Allen et al. (2025), L. Yang et al. (2025), and G. Gozaliasl et al. (2025). The results for star-forming and quiescent galaxies are shown in the top and bottom panels, respectively. It noted that the results by G. Gozaliasl et al. (2025) are for the brightest group galaxies.
