“Evolution and Signatures of Primordial Magnetic Fields”

Astrophysical observations show that the various structures of the Universe, such as galaxies, galaxy clusters, and intergalactic medium, are permeated by large-scale correlated magnetic fields. There exists a commonly accepted hypothesis that relatively strong galaxy and galaxy cluster magnetic fields are produced from the amplification of much weaker pre-existing seed fields. The origin of these seed fields still remains unknown. There are two scenarios currently under debates: an astrophysical scenario, where the seed is typically very weak and magnetic field is transferred from local sources within galaxies to larger scales, and a cosmological scenario where a significant seed field is generated prior to galaxy formation in the early Universe on scales that are large now.

We aim to study the evolution and signatures of primordial magnetic fields during the expansion of the Universe and its effects on the large-scale structure (LSS) formation. We will use ENZO – MHD, adaptive mesh refinement, hybrid code to determine the main statistical characteristics of the outcome cosmological magnetic fields, such as their strength and correlation lengths. We will use different initial conditions in correspondence with various magnetogenesis scenarios. Our theoretical predictions will be compared with the observational data. Our findings will enable us (hopefully) to limit the number of magnetogenesis scenarios.

” The Lehmann-Haupt International Doctoral Program gives me a great opportunity not only to study/do research on my subject and get experience abroad, but also to become a part of that big community which science is founded on. The Georg-August-University of Göttingen is really a new world for me where research institutes are very close to each other and it gives me the chance to become familiar with the researches other students do. I myself was observing not only the Moon and Saturn from my institute’s observatory but I was also able to see cancer cells in the Institute of Biology. Göttingen and Ilia State Universities together create an environment where you will never feel alone while doing your PhD. “
