Tangled, primordial cosmic magnetic fields create small rotational velocity perturbations on the last scattering surface (LSS) of the cosmic microwave background radiation (CMBR). Such perturbations can contribute significantly to the CMBR temperature and polarization anisotropies at large l > 1000 or so, like the excess power detected by the Cosmic Background Imager (CBI) experiment. The magnetic contribution can be distinguished from most conventional signals, as they lead to CMBR… Expand

Cosmic microwave background trispectrum and primordial magnetic field limits.
TLDR
A new measure of magnetic non-gaussianity, the CMB trispectrum, on large angular scales, is computed via the Sachs-Wolfe effect, which represents the tightest limit so far on the strength of primordial magnetic fields, on Mpc scales, and is better than limits from the C MB bispectrum and all modes in theCMB power spectrum.
