Spitzer /IRAC imaging has revealed that the brightest 𝑧 ∼ 7 − 8 galaxies often exhibit young ages and strong nebular line emission, hinting at high ionizing efficiency among early galaxies. However, IRAC’s limited sensitivity has long hindered efforts to study the fainter, more numerous population often thought largely responsible for reionization. Here we use CEERS JWST /NIRCam data to characterize 118 UV-faint (median M UV = − 19 . 6) 𝑧 ∼ 6 . 5 − 8 galaxies. We find that the SEDs are typically…
