On Adiabatic Renormalization of Inflationary Perturbations
Ruth Durrer, Giovanni Marozzi, Massimiliano Rinaldi
We discuss the impact of adiabatic renormalization on the power spectrum of scalar and tensor perturbations from inflation. We show that adiabatic regularization is ambiguous as it…
Can the observed large scale magnetic fields be seeded by helical primordial fields?
Chiara Caprini, Ruth Durrer, Elisa Fenu
Gravitational wave production induces a strong constraint on the amplitude of a primordial magnetic field. It has been shown that the nucleosynthesis bound for a stochastic gravita…
CMB anisotropies from acausal scaling seeds
Sandro Scodeller, Martin Kunz, Ruth Durrer
We investigate models where structure formation is initiated by scaling seeds: We consider rapidly expanding relativistic shells of energy and show that they can fit current CMB an…
