abstract

  • ABSTRACT Scaling laws of dust, Hi gas, and metal mass with stellar mass, specific star formation rate, and metallicity are crucial to our understanding of the build-up of galaxies through their enrichment with metals and dust. In this work, we analyse how the dust and metal content varies with specific 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 multidimensional parameter space. We find that these scaling laws for galaxies with 1.0 logMHi/M 0 can be reproduced using closed-box models with high fractions (3789${{
    m per cent}}$) of supernova dust surviving a reverse shock, relatively low grain growth efficiencies (=3040), and long dust lifetimes (12Gyr). The models have present-day dust masses with similar contributions from stellar sources (5080${{
    m per cent}}$) and grain growth (2050${{
    m per cent}}$). Over the entire lifetime of these galaxies, the contribution from stardust (<90${{
    m per cent}}$) outweighs the fraction of dust grown in the interstellar medium (>10${{
    m per cent}}$). Our results provide an alternative for the chemical evolution models that require extremely low supernova dust production efficiencies and short grain growth time-scales to reproduce local scaling laws, and could help solving the conundrum on whether or not grains can grow efficiently in the interstellar medium.
