[C II] 158 μm luminosity versus the UV+IR SFR. The yellow star shows the upper limit of z7_GSD_3811 assuming a line-width of 100 km s⁻¹, while the dash and arrow show the upper limit obtained if we assume a line-width of 400 km s⁻¹. The pink line and orange dashed line show the relation for local HII/starburst galaxies and metal-poor dwarf galaxies by De Looze et al. (2014), where the shaded regions correspond to the 1σ dispersion in the relations. The dotted and dash-dotted lines show the relations from the ALPINE-ALMA survey, derived by Schaerer et al. (2020, see text). The dark gray circles show objects from the compilation by Matthee et al. (2019) with z >  6. For BDF-3299 and SXDF-NB1006-2, we show updated [C II] measurement from Carniani et al. (2020). For this sample, we have rescaled the upper limits to line-widths of 100 km s⁻¹. A few galaxies from the compilation that are also detected in [O III] are indicated by their names and a lighter gray color. All upper limits are at the 3σ level.
