Early Results from GLASS-JWST XXIII: The transmission of Lyman-alpha from UV-faint z ~ 3-6 galaxies

Lyman-alpha (Ly\alpha) emission from galaxies can be used to trace neutral hydrogen in the epoch of reionization, however, there is a degeneracy between the attenuation of Ly\alpha in the intergalactic medium (IGM) and the line profile emitted from the galaxy. Large shifts of Ly\alpha redward of systemic due to scattering... Show more
