The size measured in F200W, plotted against the UV magnitude, measured from the spectrum at λ_rest = 150 nm. We also show size–luminosity derived for local spiral galaxies from R. S. de Jong & C. Lacey (2000) for which we use a magnitude correction M_UV–M_I = 1.0, and LBGs at z ∼ 8 (T. Shibuya et al. 2015; R. Kawamata et al. 2018; R. J. Bouwens et al. 2022) and z ∼ 9–12 (L. Yang et al. 2022). In addition we show star-forming complexes (Z. Chen et al. 2023) with z_phot ∼ 6–8. Finally, we show extremely compact sources, recently detected through lensing with JWST, reported in L. J. Furtak et al. (2024; R_e < 35 pc, z = 7.0), M. W. Topping et al. (2024; R_e < 22 pc, z = 6.1), and H. Williams et al. (2023; R_e = 16 pc, z = 9.5). Finally we show the upper limit of ≲100 pc reported for the brightest LRDs (H. B. Akins et al. 2024; see the text).
