Effective radius (reff) as a function of star formation rate surface density (ΣSFR) for galaxies at z > 10 with MIRI constraints on EW0 (Hβ+[O III]) (color-coded, from Castellano et al. 2022; Goulding et al. 2023; Tacchella et al. 2023; Calabrò et al. 2024; Carniani et al. 2024; Álvarez-Márquez et al. 2025; Helton et al. 2026; Zavala et al. 2025; Harikane et al. 2026, and Álvarez-Márquez et al. 2026). The symbols denote individual sources, and the open symbols indicate sources without available EW0 measurements (Arrabal Haro et al. 2023; Naidu et al. 2026). U37126 (star) occupies the compact high-ΣSFR regime, but shows unusually weak nebular emission with EW0 (Hβ+[O III]) < 296 Å (3σ) compared to other compact systems (e.g., GNz11 and GHz2), consistent with a high LyC escape fraction.
