  • We present simulations of the magnetized interstellar medium (ISM) in models of massive star-forming (40 M ☉ yr–1) disk galaxies with high gas surface densities (Σgas ~ 100 M ☉ pc–2) similar to observed star-forming high-redshift disks. We assume that type II supernovae deposit 10% of their energy into the ISM as cosmic rays (CRs) and neglect the additional deposition of thermal energy or momentum. With a typical Galactic diffusion coefficient for CRs (3 × 1028 cm2 s–1), we demonstrate that… CONTINUE READING
