Description
This lecture introduces cosmological magnetic fields. As they could already have been generated in the early Universe, their observational signatures offer unique insights into fundamental physics. The lecture begins by outlining the essential tools for modeling magnetized fluids, with a particular focus on magnetohydrodynamics (MHD) and MHD turbulence. Then, the discussion shifts to high-energy MHD, which is relevant for the very early Universe plasma. Here, macroscopic quantum effects are incorporated into the models, which significantly affects the evolution of primordial magnetic fields. Finally, the lecture examines the broader potential cosmological implications of primordial magnetic fields, with a specific example of their impact on the formation of dwarf galaxies.
