Rest-frame U − V vs. V − J diagrams, color coded by R_e at 5 × 10¹⁰ M_⊙ (top panels) and Sérsic (n) parameter (bottom panels), with each column representing a different redshift bin. Post-starburst galaxies primarily exist beyond z = 1. SED type 6, the youngest post-starburst type, is only found at z > 1.5 in our sample, and significantly more compact than all other galaxies at the same redshift. Post-starburst SED type 7 is slightly older and more similar in size to quiescent galaxies. The galaxies in between the star-forming and quiescent sequences have similar (z < 1) or slightly larger sizes (z > 1) than quiescent galaxies.
