Primordial tangled cosmological Magnetic Fields source rotational velocity perturbations of the baryon fluid, even in the post-recombination universe. These vortical modes inturn leave a characteristic imprint on the temperature anisotropy of the Cosmic Microwave Background (CMB), if the CMB photons can be rescattered after recombination. Observations from WMAP indicate that the Universe underwent a relatively early reionization (z{sub ri}{approx}15), which does indeed lead to a significant… Expand

We compute the secondary cosmic microwave background radiation (CMBR) anisotropy signal from the reionization of the Universe in the presence of tangled magnetic fields. We consider theExpand

Stringent Limit on Primordial Magnetic Fields from the Cosmic Microwave Background Radiation.
Using numerical compressible MHD calculations and a Monte Carlo Markov chain analysis, which compares calculated CMB anisotropies with those observed by the WMAP and Planck satellites, limits are derived on the magnitude of putative PMFs. Expand

We consider the impact of a stochastic background of primordial magnetic fields with non-vanishing helicity on CMB anisotropies in temperature and polarization. We compute the exact expressions forExpand
Cosmic strings as the source of small-scale microwave background anisotropy
Cosmic string networks generate cosmological perturbations actively throughout the history of the universe. Thus, the string sourced anisotropy of the cosmic microwave background is not affected byExpand
A complete 3D numerical study of the effects of pseudoscalar–photon mixing on quasar polarizations
We present the results of three-dimensional simulations of quasar polarizations in the presence of pseudoscalar–photon mixing in the intergalactic medium. The intergalactic magnetic field is assumedExpand
Extracting the spectral index of the intergalactic magnetic field from radio polarizations
We explain the large scale correlations in radio polarization in terms of the correlations of galaxy cluster/supercluster magnetic field. Assuming that the polarization correlations closely followExpand
Magnetized CMB anisotropies
Possible effects of large-scale magnetic fields on the cosmic microwave background (CMB) are reviewed. Depending on the specific branch of the spectrum of plasma excitations, magnetic fields areExpand

Magnetic fields of galaxies
Intensity of galactic magnetic field is minute. it is measured in microgausses. However, the field has a record scale measured in ki-loparsecs. (Unfortunately, the Guinness book does not mention thisExpand
