A JWST/NIRCam study of key contributors to reionization: the star-forming and ionizing properties of UV-faint z ∼ 7−8 galaxies

ABSTRACT Spitzer/Infrared Array Camera (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 faint...
