Brief Description of the Doctoral Project:

„The Evolution of Cosmological Magnetic Fields in expanding Universe“

My primary interest and motivation for my PhD project is cosmological magnetic fields and their evolution. The presence of magnetic fields in galaxies and galaxy clusters plays a crucial role in modern astrophysical studies. Observations show that galaxies have magnetic fields with a component that is coherent over a large fraction of the galaxy. However, the origin of observed cosmic magnetic fields still remains unknown. One of the common hypothesis is that relatively strong galactic and galactic cluster magnetic fields are produced from the amplification of much weaker pre-existing ‘’seed’’ fields. Understanding the origin of these seed fields itself is one of the challenging and interesting questions of modern astrophysics.
The evolution of primordial magnetic field is complex process requiring MHD equations  and during my PhD project I am going to perform direct numerical simulations to study the effects of the large scale structure on magnetic field and vice versa - the effects of the magnetic fields on the large scale structure. We will be using Cosmological MHD simulations evolving magnetic field from early universe. At first we are going to investigate effects of initial conditions and see if these initial conditions can “survive” during gravitational instability (i.e. if the initial conditions are reflected in the final configurations of the field, and are not “erased” through nonlinear processes). If the resulting magnetic field characteristics retain information on certain initial conditions, then we will investigate further the recovering of the initial conditions that ‘’formed” presently observed magnetic fields. We will be interested in particular of the large scale correlated magnetic fields in the clusters of galaxy, and we will check if the characteristics of these fields agree with observational data.
