Left: A_V attenuation as a function of sSFR⁻¹. Galaxies with 6 <  z <  12 are binned with the UV β slope (circles). The solid black line is the linear fit of these binned points. Predictions of the linear A_V-sSFR⁻¹ relation at a fixed SFR surface density from Langeroodi et al. (2024) are indicated with dashed coloured lines. The stacked points obtained by Langeroodi et al. (2024) are shown as cyan hexagons. Right: Same as in the left panel but using the A_V and sSFR⁻¹ obtained with the UV-NIR SED fit; that is, without ALMA constraints.
