sM_Gas plotted against sSFR for the ALPINE galaxies assuming a Chabrier (left) and THIMF (right). The circles represent galaxies detected via [CII], while the upper limits on gas mass are shown as inverse triangles. Evolutionary models (solid and dotted lines) are plotted for different final ages (increasing from right to left). The figure shows the case with [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. All models are color-coded by the predicted metallicity and illustrate the effect of varying η_out from 0 (solid curves) to 2 (dotted curves).
