JADES: Rest-frame UV-to-NIR Size Evolution of Massive Quiescent Galaxies from Redshift z = 5 to z = 0.5

Abstract We present the UV-to-near-IR (NIR) size evolution of a sample of 161 quiescent galaxies with M * > 10 10 M ⊙ over 0.5 < z < 5. With deep multiband NIRCam images in GOODS-South from JADES, we measure the effective radii ( R e ) of the galaxies at rest-frame 0.3, 0.5, and 1 μ m. On average, we find that quiescent galaxies are 45% (15%) more compact at rest-frame 1 μ m than they are at 0.3 μ m (0.5 μ m). Regardless of wavelengths, the R e of quiescent galaxies strongly evolves with redshift, and this evolution depends on stellar mass. For lower-mass quiescent galaxies with M * = 10 10 –10 10.6 M ⊙ , the evolution follows R e ∝ (1 + z ) −1.1 , whereas it becomes steeper, following R e ∝ (1 + z )…
