On the Measurement of the Helicity of Intergalactic Magnetic Fields Using Ultra-High-Energy Cosmic Rays
Rafael Alves Batista, Andrey Saveliev
The origin of the first magnetic fields in the Universe is a standing problem in cosmology. Intergalactic magnetic fields (IGMFs) may be an untapped window to the primeval Universe…
Stringent Limit on Primordial Magnetic Fields from the Cosmic Microwave Background Radiation
Karsten Jedamzik, Andrey Saveliev
Primordial magnetic fields (PMFs), being present before the epoch of cosmic recombination, induce small-scale baryonic density fluctuations. These inhomogeneities lead to an inhomo…
Evolution of Helical Cosmic Magnetic Fields as Predicted by Magnetohydrodynamic Closure Theory
Andrey Saveliev, Karsten Jedamzik, Guenter Sigl
We extend our recent derivation of the time evolution equations for the energy content of magnetic fields and turbulent motions for incompressible, homogeneous, and isotropic turbu…
Time Evolution of the Large-Scale Tail of Nonhelical Primordial Magnetic Fields with Back-Reaction of the Turbulent Medium
Andrey Saveliev, Karsten Jedamzik, Guenter Sigl
We present a derivation of the time evolution equations for the energy content of nonhelical magnetic fields and the accompanying turbulent flows from first principles of incompres…
