Supernova driven turbulence: Magnetic field and multiphase structure of the interstellar medium
  Nordita Astrophysics seminars

Wednesday 01 February 2017
from 13:30 to 14:30
at 112:028
Speaker : Frederick Gent (Aalto University)
Abstract : Using direct numerical simulations of the interstellar medium (ISM) stirred and heated by supernova explosions in rotating disk galaxies, we investigate its thermal structure. The model is the first to invoke a dynamo, which includes large scale and small scale dynamo in the ISM, which advances investigation of how the magnetic field is generated in disk galaxies and how the features of the magnetic field interact with the multiphase structure of the ISM. We consider local averaging techniques, as an alternative to horizontal averages, to understand the separation of scales in the magnetic field, velocity field, etc. over arbitrary domains.
