We gather JWST data from the CEERS survey in the Extended Groth Strip, jointly with HST data, and analyze spatially resolved optical-to-mid-IR spectral energy distributions to estimate photometric redshifts in two dimensions and stellar population properties on a pixel-by-pixel basis for red galaxies detected by NIRCam. We select 138 galaxies with F150W-F356W>1.5mag and F356W<27.5mag. The nature of these sources is threefold: (1) 71% are dusty star-forming galaxies (SFGs) at 2<z<6 with 9<logM_*_/M_{sun}_<11 and a variety of specific SFRs (<1 to >100 Gyr-1); (2) 18% are quiescent/dormant (i.e., subject to reignition/rejuvenation) galaxies (QGs) at 3<z<5, with logM_*_/M_{sun}_~10 and poststarburst mass-weighted ages (0.5-1.0Gyr); and (3) 11% are strong young starbursts with indications of high equivalent width emission lines (typically, [OIII]+H{beta}) at 6<z<7 (XELG-z6) and logM_*_/M_{sun}_~9.5. The sample is dominated by disk-like galaxies with remarkable compactness for XELG-z6 (effective radii smaller than 0.4kpc). Large attenuations in SFGs, 2<A(V)<5mag, are found within 1.5 times the effective radius, approximately 2kpc, while QGs present A(V) ~0.2mag. Our SED-fitting technique reproduces the expected dust emission luminosities of IR-bright and submillimeter galaxies. This study implies high levels of star formation activity between z~20 and z~10, where virtually 100% of our galaxies had already formed 10^8^M_{sun}_, 60% had assembled 10^9^M_{sun}_, and 10% up to 10^10^M_{sun}_ (in situ or ex situ).2023ApJ...946L..16Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/946/L16CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)I/337 : Gaia DR1 (Gaia Collaboration, 2016)J/MNRAS/338/508 : Phot+spectroscopy of UCM galaxies (Perez-Gonzalez+, 2003)J/ApJ/622/772 : Redshift survey of submillimeter galaxies (Chapman+, 2005)J/ApJ/675/234 : Stellar mass functions for z<4 gal.
