Description
Outflows and the structure of the ISM in high-redshift galaxies
Recent observations of high-redshift galaxies indicate that the conditions in their ISM are distinctively different to local galaxies. High formation rates of stars embedded in an extremely dense and highly turbulent interstellar medium with high molecular gas fractions and strong gas outflows are ubiquitous. We present new high-resolution sub-parsec scale adaptive mesh simulations of stratified disks to demonstrate how rapidly H2 and CO molecules can form in such an extreme environment and how the evolution and subsequent explosions of massive stars shape the ISM and drive turbulence as well as mass-loaded outflows in agreement with current observations at redshifts z ~ 1 - 2. For this project we acknowledge support from DFG priority program 1573.
