JWST data shows half-light radii larger than half-mass radii in galaxies at 0.2<z<2.5, with mass-dependent differences, steeper size-mass slopes for light, and faster mass-size growth for star-forming galaxies at high redshift.

The multiwavelength structure of post-starburst galaxies at 0.5 < z < 3 with JWST PRIMER: compact morphologies and residual disturbances
Post-starburst galaxies show compact morphologies with minimal wavelength-dependent structural change and low overall disturbance levels, except for enhanced residual asymmetry in massive systems at z > 1, supporting two distinct quenching pathways.

Difference Between Half-mass Radius and Half-light Radius of Galaxies at 0.2 $< z <$ 2.5 Revealed by JWST/NIRCam Data
JWST data shows half-light radii larger than half-mass radii in galaxies at 0.2<z<2.5, with mass-dependent differences, steeper size-mass slopes for light, and faster mass-size growth for star-forming galaxies at high redshift.
