Faraday Rotation Measures dependence with galaxy clusters dynamics

We confirm magnetic fields presence in galaxy clusters by calculating the excess of faraday rotation measurements (RM) in their line of sight direction. This is well known fact, however, we found a different behavior in the RM distributions if we divide the Galaxy Clusters by their dynamical state. We found an excess of RM in the case of relaxed clusters. This can be explained by the fact of "Cooling Core" events. It also tell us about that the merging process is not as efficient dynamo as the cooling flows or small scale turbulent dynamo driven by radiative cooling in the relaxed cases.
