Rest-frame U − V vs. V − J diagrams. The black solid box isolates quiescent from star-forming galaxies. Panel (e) further shows the distinction between post-starburst and older quiescent galaxies in the quiescent box. Each datapoint represents an SED type, with the numbers indicated in panel (e). The symbol size reflects the number of galaxies per type. Color coding indicates sSFR (a, see color bar Figure 1) Hα equivalent width (b) R_e at 5 × 10¹⁰ M_⊙ (c) and 2 × 10¹⁰ M_⊙ (d) and Sérsic n index (f). This figure illustrates the distinct structures of star-forming and quiescent galaxies, with R_e decreasing and n increasing when moving from the star-forming to the quiescent sequence. Furthermore, size increases when moving up the quiescent sequence, with post-starburst galaxies being significantly smaller than all other galaxy types.
