Cosmic evolution of grain size distribution in galaxies using the $ν^2$GC semi-analytic model

Abstract:We investigate the cosmological evolution of interstellar dust with a semi-analytical galaxy formation model (𝜈 2 GC), focusing on the evolution of grain size distribution. The model predicts the statistical properties of dust mass and grain size distribution in galaxies across cosmic history. We confirm that the model reproduces the relation between dust-to-gas ratio and metallicity in the local Universe, and that the grain size distributions of the Milky Way (MW)-like sample become similar to the so-called … Show more
