Integrated FIR SEDs of our sample of high-z structures, which are fitted with dust models (grey curve; Magdis et al. 2012) and, in the case of COS-SBC6, a mid-IR AGN template (yellow; Mullaney et al. 2011) (see Section 5.2). We show the best-fit SFR, dust mass, and radiation field ⟨U⟩ in each panel. We note that the radio photometry is not included in the fitting; instead we extrapolated a radio component from IR luminosity using the IR-radio relation from Delvecchio et al. (2021).
