O32 line ratio vs. M_UV. The candidates in our sample with JWST spectra showing detectable emission lines are represented by black stars when both lines are detected, and they are represented with arrows when we have the [O III] measurement and [O II] is just an upper limit. The known leakers at z ∼ 0 and z ∼ 3 (Flury et al. 2022b; Vanzella et al. 2020; Marques-Chaves et al. 2022) are shown color-coded as a function of their measured f_esc. The gray line (O32 = 5) indicates the threshold for LCEs proposed by Flury et al. (2022b). The typical error is shown below the legend.
