JWST spectroscopy of 295 galaxies at 5.5 < z < 14.3 shows UV slope beta reddening at z > 9.5, with lack of dust as the main driver of bluer values and nebular continuum at T > 15,000 K able to reproduce the observed range without dust.

Hitting the slopes: A spectroscopic view of UV continuum slopes of galaxies reveals a reddening at z > 9.5
