Abstract
Scaling laws of dust, Hi gas and metal mass with stellar mass, speci?c star formation rate and metallicity are crucial to our understanding of the buildup of galaxies through their enrichment with metals and dust. In this work, we analyse how the dust and metal content varies with speci?c gas mass (MHI M?) across a diverse sample of 423 nearby galaxies. The observed trends are interpreted with a set of Dust and Element evolUtion modelS (DEUS) ? including stellar dust production, grain growth, and dust destruction ? within a Bayesian framework to enable a rigorous search of the multi-dimensional parameter space. We ?nd that these scaling laws for galaxies with ?1.0 . logMHI M? . 0 can be reproduced using closed-box models with high fractions (37-89\%) of supernova dust surviving a reverse shock, relatively low grain growth e?ciencies (=30-40), and long dust lifetimes (1-2Gyr). The models have present-day dust masses with similar contributions from stellar sources (50-80\%) and grain growth (20-50\%). Over the entire lifetime of these galaxies, the contribution from stardust (\ensuremath
