Lyα escape fraction as a function of the LyC escape fraction inferred from the combination of spectroscopic properties using the relation derived by Mascia et al. (2024). Symbols are the same as in Fig. 7. The left panel includes all post-reionization galaxies (z < 5.5) while the right panel includes galaxies residing in a partially ionized IGM. For comparison, we report with the solid green line and region the best fitting relation found by Begley et al. (2024) for z ∼ 4 − 5 emitters.
