The ultraviolet continuum slopes of high-redshift galaxies: evidence for the emergence of dust-free stellar populations at z > 10

F. Cullen, D. J. McLeod, R. J. McLure +11

We present an analysis of the ultraviolet (UV) continuum slopes ($\beta$) for a sample of $172$ galaxy candidates at $8<z_{\mathrm{phot}}<16$ selected from a combination of JWST NI…
