Abstract

Cosmic reionization represents the first epoch when galaxies affect the bulk properties of the universe. Extensive programs with HST have established that galaxy populations at redshifts z>6 are likely abundant and luminous enough to reionize the IGM during the first billion years after the Big Bang. The critical remaining issue is to constrain separately the production rate of Lyman continuum (LyC) photons per unit UV luminosity and the fraction f_esc that escape to reionize the IGM. HST has the unique capability to measure LyC directly from systems as distant as z~3 via WFC/UVIS F336W, but this critical capability will not be possible with JWST and is required to quantify the importance of future reionization epoch galaxies it discovers. The measurement of LyC with HST at z7.
