Dynamo driven magnetic fields in the interstellar medium

Description

We model supernova (SN) driven turbulence in the multi-phase interstellar medium (ISM) to explore the dynamo in a differen- tially rotating section of the galactic disk. Using a small seed field SN explosions drive a turbulent dynamo and the rotation & shear drive a large scale dynamo, the interactions of which have been poorly understood and rarely included in dynamo modelling. Our resulting field is, therefore, physically derived and embedded differentially within the cold (∼100 K), warm (∼10^4 K) and hot (∼10^6 K) phases of the ISM, and exhibits scale separation between its random and large scale components.
