Generalized CMB initial conditions with pre-equality magnetic fields

The most general initial conditions of CMB anisotropies, compatible with the presence of pre-equality magnetic fields, are derived. When the plasma is composed by photons, baryons, electrons, CDM particles and neutrinos, the initial data of the truncated Einstein-Boltzmann hierarchy contemplate one magnetized adiabatic mode and four (magnetized) non-adiabatic modes. After obtaining the analytic...

Cosmological 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...

Magnetized initial conditions for CMB anisotropies

This paper introduces a systematic treatment of the linear theory of scalar gravitational perturbations in the presence of a fully inhomogeneous magnetic field. The analysis is conducted both in the synchronous and in the conformally Newtonian gauges. The cosmological plasma is assumed to be composed of cold dark mattter, baryons, photons, neutrinos. The problem of super-horizon initial conditi...

Cosmic 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...

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...
