The Far-Ultraviolet Continuum Slope as a Lyman Continuum Escape Estimator at High-redshift
J. Chisholm, A. Saldana-Lopez, S. Flury +25
Most of the hydrogen in the intergalactic medium (IGM) was rapidly ionized at high-redshifts. While observations have established that reionization occurred, observational constrai…
