Comparison of R23 and O32 ratios of LAEs with the general galaxy populations inferred from NIRSpec observations at z ≳ 6. Orange circles show JADES Deep galaxies from Cameron et al. (2023) which are not LAEs. Diamonds and pentagons show measurements from individual lensed galaxies at z ≳ 5 (Mascia et al. 2023; Nakajima et al. 2023). Measurements from stacked galaxies at z ∼ 5.6 − 7.7 are shown as hollow purple markers (Sanders et al. 2023; Tang et al. 2023). Also shown are measurements from SDSS for z < 0.1 star-forming galaxies (Aihara et al. 2011). Overall, we find that our faint LAEs occupy a similar parameter to that occupied by the general star-forming galaxy population at z ≳ 6. This also highlights that the observed presence of Lyα emission in reionization era galaxies is driven by external factors, and not necessarily by the ISM/stellar properties of the galaxies. Interestingly, UV-faint LAEs from our sample tend to show higher O32 and lower R23 ratios than the UV-bright ones.
