Two-dimensional histogram (blue) of the galaxy distribution with stellar mass ∼5 × 10¹⁰ M_⊙. The orange contours enclose 25%, 50%, and 75% of the sample. The solid red line indicates the best-fitting relation derived in Section 4.2. To facilitate comparison with previous studies, the results from van der van der Wel et al. (2014), derived from rest-frame 0.5 μm sizes, are shown as black squares, and those from Martorano et al. (2024), derived from rest-frame 1.5 μm sizes, are shown as red stars.
