Description
Star formation driven outflows play an important role regulating the gas supply of galaxies, thus regulating the star formation. However, we still need a consensus on the details of this feedback process, particularly in starbursting environments. I will present results from the DUVET sample of local starbursting galaxies observed using the IFU KCWI/Keck. We measure ionised gas outflows in 10 face-on galaxies with ~1000 individual measurements at 500pc resolution. Using our observations (1) we can discriminate between widely used models of the outflow launching mechanism. (2) We derive much-needed scaling relations for the relationship between star formation and outflow properties across a range of star-forming environments and compare these to simulations. (3) We compare to observations from NOEMA, and connect the outflows with location in the resolved Kennicutt-Schmidt relation to find that starburst regions remove more gas via the outflow than they convert into stars. This directly measures how outflows regulate star formation and may contribute to quenching. DUVET's resolved outflow observations provide a new perspective to make ground-breaking constraints on how stellar feedback regulates star formation.
