SUMMARY:Magnetic Fields and Cosmic Rays in Galaxy Clusters\, Astronomy
  Colloquium\, Klaus Dolag\, Max Planck Institute for Astronomy
DESCRIPTION:In galaxy clusters\, non-thermal components such as magnet
 ic field and high energy particles keep a record of the processes acti
 ng since early times till now. These components play key roles by cont
 rolling transport processes inside the cluster atmosphere and therefor
 e have to be understood in detail. However including them in simulatio
 ns is extremely challenging as the structures in and around clusters a
 re 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 pred
 ictions for the magnetic field structure for different models of magne
 tic seed fields. This allows us to put constrains on the presence of c
 osmic ray protons in galaxy clusters by comparing in detail the induce
 d radio emission in these simulations with observations. Additional\, 
 such simulations can be used to constrain the transport and the deflec
 tion of UHECRs within clusters and large scale structures.
