A Bending in the Size–Mass Relation of Star-forming Galaxies across 0.5 < z < 6.0 at a Critical Stellar Mass of 1010M⊙ Revealed by JWST

We investigate the rest-frame optical size–stellar mass relation of galaxies at 0.5 <  z  < 6.0 using deep JWST/NIRCam and MIRI imaging from the PRIMER survey. We find that star-forming galaxies (SFGs) exhibit a broken power-law relation at all redshifts, with a nearly constant pivot mass ( M...
