Redshift evolution of the dust mass to observed UV luminosity relation. Left: relation between the dust mass and the UV luminosity for the Salpeter IMF (red) and evolving IMF (blue). Coloured thick solid lines depict the medians of the distributions of dust masses (coloured contours) at a given UV luminosity. Vertical black solid and dashed lines denote the UV luminosity threshold in the evolving IMF and Salpeter IMF simulations, respectively, below which the UV luminosities have not converged for all galaxies due to the mass resolution limit of the VSMDPL simulation. Right: redshift evolution of the dust mass-to-UV luminosity ratio for different dust mass bins with a width of 1 dex for the Salpeter IMF (dashed lines) and evolving IMF (solid lines) models. The values in the panel show the central value of each dust mass bin.
