Creation of cosmological magnetic fields in a bouncing cosmology

Abstract

We show (in a completely analytical and exact manner) that an efficient magnetic field amplification method is operative during the bounce in a time-dependent gauge coupling model. The cosmological magnetic fields so generated have particular spectral features, and may be observed by future CMB measurements and by direct cluster measurements.
