Final Report Abstract

Galaxy clusters are the largest, quasi-equilibrium objects in the Universe, making them extraordinarily interesting for cosmology and astrophysics. In these systems, non-thermal components such as magnetic field 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 are sources of additional pressure and energy support. The evolution and the structure of magnetic fields can be explored and within fully self consistent, cosmological MHD simulations. The resulting magnetization of the ICM will is the compared with recent observations in radio band. The inferred magnetization of the large scale structure of the universe is compared with recent findings of the propagation of high energy cosmic messenger particles.
