Faraday Rotation Measure Dependence on Galaxy Clusters Dynamics
  We study the magnetic fields in galaxy clusters through Faraday rotation
measurements crossing systems in different dynamical states. We confirm that
magnetic fields are present in those systems and analyze the difference between
relaxed and unrelaxed samples with respect to the dispersion between their
inherent Faraday Rotation measurements. We found an increase of this RM
dispersion and a higher RM overlapping frequency for unrelaxed clusters. This
fact suggests that a large scale physical process is involved in the nature of
unrelaxed systems and possible depolarization effects are present in the
relaxed ones. We show that dynamically unrelaxed systems can enhance magnetic
fields to large coherence lengths. In contrast, the results for relaxed systems
suggests that small-scale dynamo can be a dominant mechanism for sustaining
magnetic fields, leading to intrinsic depolarization.
