Observed redshift evolution of M_dust. Individual values are displayed with circles, coloured with corresponding L_IR. Binned means are shown with black circles and associated 1σ errors. For comparison, we also show the mean M_dust for a large sample of dusty galaxies up to z ∼ 0.5 (Driver et al. 2018, black inverted triangle). The black dashed and dotted lines are best regression fits from this work and from Dudzevičiūtė et al. (2020), respectively.
