Caption: Figure 7.
Galaxy size as a function of mass in four redshift bins. Data points are color coded by their location in rest-frame UVJ color–color space (blue = star forming and red = quiescent). Shaded regions show the best-fit relations from A. van der Wel et al. (2014) extrapolated to each redshift range for star-forming and quiescent galaxies (blue and red, respectively). The dashed blue line in each plot is the best-fit linear relation for star-forming galaxies using the CEERS data. Some of the most compact sources at high z are identified as “Little Red Dots” (LRDs; D. D. Kocevski et al. 2025) and are excluded from the fit. The PSF resolution limit is shown as the horizontal gray shaded region for each redshift range.
