Steady outflows in giant clumps of high-z disc galaxies during migration and growth by accretion

Dekel, A; Krumholz, Mark


We predict the evolution of giant clumps undergoing star-driven outflows in high-z gravitationally unstable disc galaxies. We find that the mass-loss is expected to occur through a steady wind over many tens of free-fall times (tff ∼ 10 Myr) rather than by an explosive disruption in one or a few tff. Our analysis is based on the finding from simulations that radiation trapping is negligible because it destabilizes the wind (Krumholz & Thompson 2012, 2013). Each photon can therefore contribute...[Show more]
