A redshift-dependent IRX-$\beta$ dust attenuation relation for TNG50 galaxies

Sebastian Schulz, Gergö Popping, Annalisa Pillepich +4

We study the relation between the UV-slope, $\beta$, and the ratio between the infrared- and UV-luminosities (IRX) of galaxies from TNG50, the latest installment of the IllustrisTNG ga…
