| Abstract: |
We have studied the role of magnetic fields on the evolution and dynamics of Intracluster Medium (ICM) through magnetohydrodynamics simulations. We expect that the magnetic fields that are anchored in the gravitational potential of galaxies can be considerably twisted, braided and stretched due to the motion of galaxies, and reconnect and heat the plasma trapped in the tangled fields. To this end, we have performed a simple calculation of two counter-rotating galactic disks in an ambient magnetic field parallel to the rotation axes of the disks. Through the rotation of the galactic disks, toroidal magnetic fields are produced leading to the amplification of the initial fields. The evolution creates an intermittent plasma in the intergalactic medium with hot plasma surrounded by cooler gas regions, thus causing a two-phase medium and nonuniform temperature in the ICM. |
