As in Fig. 2, but for the [O III] 88 μm line. The obtained relations from the EAGLE simulations are compared with relations derived from simulations (Olsen et al. 2018; Katz et al. 2022; Kannan et al. 2022) and observations (De Looze et al. 2014; Harikane et al. 2020; Mordini et al. 2021). Linear relations inferred from our models using only H II regions are shown as indigo solid lines over the dynamic range covered by the simulations and extrapolated to lower and higher SFRs as indigo dotted lines; the shaded area represents the 1σ error (see Appendix C).
