Stellar mass (top) and SFR (middle) as a function of effective radius. J1316+2614 is represented with a blue star. Measurements of other compilations of galaxies at z = 1 − 5 (red circles; van der Wel et al. 2012), star-forming clumps in lensed galaxies (green squares; Claeyssens et al. 2023; Fujimoto et al. 2024; Messa et al. 2024), and star clusters and YMCs at different redshifts (yellow diamonds; Norris et al. 2014; Vanzella et al. 2023; Adamo et al. 2024) are also shown. For star clusters and star-forming clumps without SFR measurements, we assume star-formation ages of 1 Myr and 10 Myr, respectively, and SFR = M_⋆/age. Bottom: ΣM_⊙ vs. ΣSFR of J1316+2614 along with other galaxies at higher redshifts (black), including very compact sources with strong nitrogen emission (violet) that exhibit abundance patterns resembling those seen in globular clusters.
