cds-question@unistra.frgalaxiesinfrared-sourcesinfrared-photometryredshiftedgalaxy-radiigalaxy-classification-systemsWe analyze 347 galaxies at redshift 4<z<9.5 using JWST observations from the Cosmic Evolution Early Release Science (CEERS) program by simultaneously fitting a two-dimensional parametric model to the seven-filter Near Infrared Camera images to measure the overall structural parameters and quantify the global properties of the galaxies in the rest-frame optical band. Particular attention is devoted to deriving robust uncertainties that include, among other factors, the influence of cosmological surface brightness dimming and resolution effects. Using the global Sersic index (n<1.5) and observed axial ratio (q<0.6) as a guide, we place a conservative lower limit of ~45% on the incidence of galactic disks. Galaxies follow a relation between the rest-frame optical luminosity and effective radius in the redshift range 4<z<9.5, as well as separately over the intervals 4<z<5 and 5<=z<9.5, with a very similar slope but a marginally lower zero-point in the higher-redshift bin (Re=0.69{\pm}0.05kpc) compared to the lower-redshift bin (Re=0.91{\pm}0.04kpc). Within the limitations of the current sample size, we find no significant redshift evolution of n or Re at these early epochs.2024ApJ...960..104Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/960/104CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)J/ApJ/453/48 : VI photometry of HST faint field galaxies (Driver+ 1995)J/ApJS/107/1 : Morphologies of distant galaxies II (Abraham+ 1996)J/ApJS/147/1 : Classification of nearby galaxies (Conselice+, 2003)J/AJ/127/131 : NICMOS early-type galaxies (Stanford+, 2004)J/ApJS/172/615 : GALFIT result for GEMS galaxies (Haussler+, 2007)J/ApJ/659/162 : CAS parameters of 199 nearby galaxies (Taylor-Mager+, 2007)J/MNRAS/382/109 : Massive galaxies in Extended Groth Strip (Trujillo+, 2007)J/ApJS/197/21 : The Carnegie-Irvine Galaxy Survey (CGS).
