Title: A low-redshift look to reionization with star-forming galaxies
 

Abstract: One of the main scientific goals for the James Webb Space Telescope (JWST) is to understand Reionization, the last major cosmic phase by which the infant Universe transitioned from a neutral to a (mostly) ionized state. The responsible sources for reionization are still under debate, but star-forming galaxies seem to be the likeliest due to their high number density at early epochs. However, directly probing ionizing (also called Lyman Continuum, LyC) radiation from distant galaxies is difficult, since the escaping photons are likely absorbed by the remaining gas in the intergalactic medium (IGM).
