Seminar topic: “Study of intergalactic magnetic fields with methods of gamma-ray astronomy”
Speaker: Alexander Korochkin (INR of RAS)
Abstract:
Magnetic fields occupying the voids of the large-scale structure of the Universe may be a relic from the Early Universe originating from either inflation or from cosmological phase transitions. Such primordial magnetic fields can be probed via measurements of secondary gamma-ray emission from gamma-ray interactions with extragalactic background light. I will discuss the prospects for the study of primordial magnetic fields with the new-generation gamma-ray telescope CTA. I will also consider two classes of systematic errors that need to be taken into account in the analysis. The first class is associated with inhomogeneities of the large-scale structure of the Universe, and the second — with inaccuracies of numerical simulations.
