Cosmology, high-energy physics and astrophysics are today converging to the study of large
scale magnetic fields. While the experimental evidence for the existence of large scale …

▪ Abstract In forthcoming years, connections between cosmology and particle physics will
become increasingly important with the advent of a new generation of cosmic microwave …

The high-temperature plasma above the electroweak scale∼ 100 GeV may have contained
a primordial hypercharge magnetic field whose anomalous coupling to the fermions induces …

We investigate hydromagnetic turbulence of primordial magnetic fields using
magnetohydrodynamics (MHD) in an expanding universe. We present the basic, covariant …

We study the effect of inhomogeneities in the matter distribution of the universe on the
Faraday rotation of light from distant QSOs and derive new limits on the cosmological …

We derive an upper limit of B 0< 3.4× 10− 9 (Ω 0 h 50 2) 1/2 G on the present strength of any
primordial homogeneous magnetic field. The microwave background anisotropy created by …

We examine the evolution of magnetic fields in an expanding fluid composed of matter and
radiation with particular interest in the evolution of cosmic magnetic fields. We derive the …

We present an analysis of the cosmological evolution of matter sources with small
anisotropic pressures. This includes electric and magnetic fields, collisionless relativistic …

A stochastic magnetic field in the early universe will produce anisotropies in the temperature
and polarization of the cosmic microwave background. We derive analytic expressions for …

Spatially varying primordial magnetic fields may be efficiently dissipated prior to the epoch of
recombination due to the large viscosity of the baryon-photon fluid. We show that this …
