[CII]/FIR as a function of FIR luminosity (left) for the three galaxies detected in the dust continuum, and as a function of Σ_FIR (right) for the one extended galaxy where the size can be measured. For comparison, we show galaxies from the SHINING survey (z ∼ 0), galaxies at z ∼ 0 and 3 < z < 6, and from the ALPINE survey (z ∼ 4–6) (Lutz et al. 2016; Spilker et al. 2016; Béthermin et al. 2020), and a scaling relation for z ≳ 3 main-sequence star-forming galaxies from Herrera-Camus et al. (2025).
