Sturm und Drang: Supernova-Driven Turbulence, Magnetic Fields, and Cosmic Rays in the Chaotic Starburst Interstellar Medium

Understand

Frequent supernova explosions in compact starburst regions are a main shaper of these regions' interstellar media (ISM).

• In most starbursts, the supernova remnants blast open a hot phase that fills the regions and launches a superwind.
• Denser starbursts are too overpressured for hot wind formation, but supernovae still stir up the ISM.
• I argue that supernovae power ubiquitous turbulence through each of the starburst ISM phases, including the hot wind, and that a fluctuation dynamo amplifies magnetic fields until they are in equipartition with the turbulence.
