Abstract

We use CEERS JWST/NIRCam imaging to measure rest-frame near-IR light profiles of >500 M_⋆>10¹⁰~M_\odot galaxies in the redshift range 0.510¹¹~M_\odot) quiescent galaxies between z=0.5 and z=2.3, again comparing R_\rmopt, \rmass~and \rmassd. We conclude that the main tenets of the size evolution narrative established over the past 20 years, based on rest-frame optical light profile analysis, still hold in the era of JWST/NIRCam observations in the rest-frame near-IR.
