Magnetic reheating
Shohei Saga, Hiroyuki Tashiro, Shuichiro Yokoyama
We provide a new bound on the amplitude of primordial magnetic fields (PMFs) by using a novel mechanism, named {\it magnetic reheating}. Before the epoch of recombination, PMFs ind…
Magnetic field spectrum at cosmological recombination revisited
Shohei Saga, Kiyotomo Ichiki, Keitaro Takahashi +1
If vector type perturbations are present in the primordial plasma before recombination, the generation of magnetic fields is known to be inevitable through the Harrison mechanism.…
CMB power spectra induced by primordial cross-bispectra between metric perturbations and vector fields
Maresuke Shiraishi, Shohei Saga, Shuichiro Yokoyama
We study temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation sourced from primordial cross-bispectra between metric perturbations and vecto…
