Star formation in extreme environments: the effects of cosmic rays and mechanical heating

Context. The molecular interstellar medium in extreme environments, such as Arp 220, but also NGC 253 appears to have extremely high cosmic ray (CR) rates (103−104    ×     Milky Way) and substantial mechanical heating from supernova driven turbulence. Aims. We explore the consequences of high CR ra...
