The origin of cosmic magnetism is one of the most fascinating topics in astrophysics and cosmology. Both a primordial or an astrophysical origin are consistent with current observations, which include upper limits on primordial magnetic seeds from the cosmic microwave background (CMB), detection of magnetic fields in large scales structures, and lower limits on the magnetisation of voids inferred by TeV blazars observations (difficult to explain by fully astrophysical seed magnetic fields). This new (hybrid) conference comprises different technical and theoretical expertises in a unique way.
Topics: magnetic fields, cosmology, blazars, filaments, voids
