Total [OIII] luminosity as a function of SFR for the High-z model (red) and Schimek et al. (2024a,b) (purple). In the top panel we compare our models to observational data from Hashimoto et al. (2018) at z = 9, Harikane et al. (2020) at z ∼ 6, Hashimoto et al. (2019) at z ∼ 7, Inoue et al. (2016) at z ∼ 7, Witstok et al. (2022) at z = 6.7 − 7, Fujimoto et al. (2024) at z = 8.5, Algera et al. (2024) at z = 7.3, Laporte et al. (2017) at z = 8.3, Tamura et al. (2019) at z = 8.31, Ren et al. (2023) at z = 7.2, Carniani et al. (2017) at z ∼ 7, Popping (2023) (upper limit) at z = 13, and Schouws et al. (2025a,b) at z = 14.2. We used the relations from Harikane et al. (2020) for z = 6 − 9, as well as the SB and high-redshift relations from De Looze et al. (2014). In the bottom panel we compare our models to the simulated values from Katz et al. (2022) (z = 6), Pallottini et al. (2019) (z = 6), Lupi et al. (2020) (z = 6), Pallottini et al. (2022) (z = 7.7), and Ramos Padilla et al. (2023) (z = 6). The relations are from the simulations of Olsen et al. (2017) (z ≃ 6) and Arata et al. (2020) (z = 6 − 9).
