Primordial magnetic field limits from cosmological data
arXiv:1009.2094 · doi:10.1103/PhysRevD.82.083005
Abstract
We study limits on a primordial magnetic field arising from cosmological data, including that from big bang nucleosynthesis, cosmic microwave background polarization plane Faraday rotation limits, and large-scale structure formation. We show that the physically-relevant quantity is the value of the effective magnetic field, and limits on it are independent of how the magnetic field was generated.
