Query: Dust entrainment in galactic winds   Winds driven by stellar feedback are an essential part of the galactic
ecosystem and are the main mechanism through which low-mass galaxies regulate
their star formation. These winds are generally observed to be multi-phase with
detections of entrained neutral and molecular gas. They are also thought to
enrich the circum-galactic medium around galaxies with metals and dust. This
ejected dust encodes information about the integrated star formation and
outflow history of the galaxy. It is therefore, important to understand how
much dust is entrained and driven out of the disc by galactic winds. Here we
demonstrate that stellar feedback is efficient in driving dust-enriched winds
and eject enough material to account for the amount of extraplanar dust
observed in nearby galaxies. The amount of dust in the wind depends on the
sites from where they are launched, with dustier galaxies launching more dust
enriched outflows. Moreover, the outflowing cold-dense gas is significantly
more dust-enriched than the volume filling hot tenuous material, naturally
reproducing the complex multiphase structure of the outflowing wind observed in
nearby galaxies. These results provide an important new insight into the
dynamics, structure, and composition of galactic winds and their role in
determining the dust content of the extragalactic gas in galaxies.
