Dust-to-gas ratio plotted against sSFR for the ALPINE galaxies assuming a Chabrier IMF (left) and a THIMF (right). Only galaxies with [CII] detections are shown. The circles represent galaxies with detected dust continuum, while the upper limits on the dust mass are indicated by inverse triangles. The evolutionary models are plotted assuming [M_Gas, ini, η_out, η_in, ϵ_SN] ∼ [3.3, 0−2, 0.6, 0.1] and [4.4, 0−2, 0.6, 0.1] for Chabrier and THIMF, respectively. The models are color-coded by predicted metallicity and illustrate the impact of varying the η_out from 0 (solid curves) to 2 (dotted curves).
