The ultraviolet continuum slopes (\mathbfβ) of galaxies at \mathbf{z\simeq8-15} from JWST and ground-based near-infrared imaging

We study the rest-frame ultraviolet (UV) continuum slopes (\beta) of galaxies at redshifts 8 < z < 15, using a combination of JWST ERO and ERS NIRcam imaging and ground-based near-infrared imaging of the COSMOS field. The combination of JWST and ground-based imaging provides a wide baseline in both redshift... Show more
