Arxiv: Remarkably Compact Quiescent Candidates at 3 < z < 5 in JWST-CEERS Published: 11/9/2023 4:25:00 PM Updated: 11/9/2023 4:25:00 PM


Paper abstract: In this letter, we measure the rest-frame optical and near-infrared sizes often quiescent candidates at 33, even aftercorrecting for potential color gradients. This suggests that the size evolutionof quiescent galaxies is steeper than previously anticipated and our currentunderstanding is biased by the limited wavelength capabilities of the\textit{Hubble Space Telescope} (HST) and the presence of negative colorgradients in quiescent galaxies.
