Linking cosmological magnetic fields from sub galactic scale to clusters of galaxies and beyond with cosmological MHD simulations
Abstract
In galaxy clusters, non-thermal components such as magnetic field, turbulence and high energy particles keep a record of the processes acting since early times till now. These components play key roles by controlling transport processes inside the cluster atmosphere and therefore have to be understood in detail. However including them in simulations is extremely challenging as the structures in and around clusters are quite complex and span a very large dynamic range in scales. I will report the status of what can be achieved in numerical simulations of the formation of galaxy clusters in cosmological context and our predictions for the magnetic field structure for different models of magnetic seed fields. This allows us to put constrains on turbulence and the propagation of high energy cosmic messenger particles in galaxy clusters and beyond.
