Comparison of the calculated fesc(LyC) using the relation from Choustikov et al. (2024) with the observed fesc(Lyα) (left, with the one-to-one relation shown as the dashed line) and Lyα velocity offset (right) for LAEs. With the exception of two LAEs from Tang et al. (2023), the fesc(LyC) we infer is always lower than fesc(Lyα), consistent with model predictions (e.g. Maji et al. 2022). Interestingly, one of our faint LAEs has fesc(LyC) > 0.2. We find that qualitatively, fesc(LyC) and Lyα velocity offset anti-correlate, but a low Lyα velocity offset does not necessarily guarantee high fesc(LyC). Similar trends were reported for low redshift LyC leaking galaxies by Izotov et al. (2021).
