Cosmological magnetogenesis

In this thesis, second-order gauge-invariant perturbation theory is used to develop a selfconsistent framework in which the non-linear coupling between inflationary gravitational waves and a large-scale magnetic field is investigated, as means of amplifying the field to within the strength limits required to support the galactic dynamo. For the purpose of performing an entirely gauge-invariant analysis, the seed field and the gravitational wave spectrum are treated as small perturbations of a Friedmann-Lemaitre-Robertson-Walker (FLRW) background.
