Primordial magnetic fields and CMB anisotropies
Possible signatures of primordial magnetic fields on the Cosmic Microwave Background (CMB) temperature and polarization anisotropies are reviewed. The signals that could be searched for include excess temperature anisotropies particularly at small angular scales below the Silk damping scale, B-mode polarization, and non-Gaussian statistics. A field at a few nG level produces temperature anisotr...
متن کاملCosmic microwave background trispectrum and primordial magnetic field limits.
Primordial magnetic fields will generate non-gaussian signals in the cosmic microwave background (CMB) as magnetic stresses and the temperature anisotropy they induce depend quadratically on the magnetic field. We compute a new measure of magnetic non-gaussianity, the CMB trispectrum, on large angular scales, sourced via the Sachs-Wolfe effect. The trispectra induced by magnetic energy density ...
متن کاملConstraining Primordial Magnetic Field from CMB Anisotropies at Higher Multipoles
The cosmological magnetic field is one of the important physical quantities which affect strongly the cosmic microwave background (CMB) power spectrum. Recent CMB observations have been extended to higher multipoles l &1000, and they resultantly exhibit an excess power than the standard model prediction in cosmological theory which best fits the Wilkinson Microwave Anisotropy Probe (WMAP) data ...
متن کاملCosmological Magnetic Fields vs . CMB
I present a short review of the effects of a cosmological magnetic field on the CMB temperature and polarization anisotropies. Various possibilities for constraining the magnetic field amplitude are discussed. Cosmological primordial seed magnetic fields were proposed to explain the existence of observed ∼ 10 −6 G magnetic fields in galaxies and clusters (see, e.g., Widrow 2002, Gio-vaninni 200...
متن کاملCosmic Magnetic Fields and the CMB
I describe the imprint of primordial magnetic fields on the CMB. I show that these are observable only if the field amplitude is of the order of B & 10G on Mpc scale. I further argue that such fields are strongly constrained by the stochastic background of gravity waves which they produce. Primordial magnetic fields, which are strong enough to be seen in the CMB, are compatible with the nucleos...
