SEDs of galaxies in this study. Photometry is from the super-deblended catalogs (Jin et al. 2018; Liu et al. 2018) and ALMA and NOEMA measurements. The dust SEDs are fitted with optically thick MBB models accounting for CMB impact on the continuum (da Cunha et al. 2013). The black (red) curve shows the best fit to the observed SED accounting (not accounting) for CMB. The blue curve marks the stellar component. We note that the radio data are not included in the fitting; we extrapolated a radio component to the dust SEDs using the IR–radio correlation from Delvecchio et al. (2021).
