Comparison to DLAs. This figure shows the relation between the metallicity and the dust-to-metal mass ratio, for the reference run (Sect. 3.2). This figure is very similar to panel d of Fig. 8: the only difference is that the y-axis has been divided by Z (related to the x-axis through Eq. (1)). We have overlaid in magenta the DLA measures from Table 6 of De Cia et al. (2016). The horizontal yellow line corresponds to the Galactic dust-to-metal mass ratio. The Bayesian correlation coefficient of the nearby galaxy sample is , with CR_95%(ρ) = [0.59, 0.68].
