Project Part A4: Dynamo models of galaxies with winds

Persons involved


We propose simulations of SN driven turbulence in the ISM, with special emphasis on the galactic wind and the effect of cosmic rays on the dynamo process. Simulations with a suf- ficient vertical extension allow the investigation of the disk-halo connection, where we expect new observational insight from observations with LOFAR. The local box simulations provide the input of the sub-grid physics for global models of galaxies. Here we will use and extend a SPH scheme with the potential of a later extension to consider single galaxies in a cosmological environment. The global simulations will providew a better understanding for the magnetisation of the IGM. Differences in the magnetic properties of grand-design spiral and dwarf galaxies will be illuminated with the numerical experiments.
