Effect of outflow on the sM_dust–sSFR relation. The data are identical to panel c of Fig. 14. The colored lines represent our dust evolution model. We have fixed all the parameters close to their maximum a posterior values, except the outflow rate, δ_out: τ_SFH = 0.8 Gyr, ψ₀ = 40 M_⊙ yr⁻¹, δ_in = 1.0, δ_SN = 0.01, ϵ_grow = 4500, and . The different lines correspond to different values of δ_out. The top axis displays the age of the galaxy corresponding to the particular SFH of the model run. We have used a Salpeter (1955) IMF.
