Evolution of galaxy sizes as a function of redshift. The plots show the Sérsic effective radius r_e (left), the disk effective radius r_disk (center), and the bulge effective radius r_bulge (right) as a function of z_phot for log M_★/M_⊙ > 10 galaxies. This corresponds to a mean mass of ≈ 4 × 10¹⁰ M_⊙. The points with error bars show the mean and 1 σ at a given redshift for all galaxies (black), disk-dominated galaxies (blue), and bulge-dominated galaxies (red). The r_e evolution is modeled in the left panel for all galaxies, as well as for the bulge- and disk-dominated populations, following r_e = R(1 + z)^a (see Sect. 4.2). We compare the size evolution for all galaxies with previous JWST-based work from Varadaraj et al. (2024), Ormerod et al. (2024), Allen et al. (2025) and Yang et al. (2025).
