Journal ArticleDOI
Astrophysical magnetic fields and nonlinear dynamo theory
TL;DR: The current understanding of astrophysical magnetic fields is reviewed in this paper, focusing on their generation and maintenance by turbulence, where analytical and numerical results are discussed both for small scale dynamos, which are completely isotropic, and for large scale dynamo, where some form of parity breaking is crucial.
Journal ArticleDOI
The origin, evolution and signatures of primordial magnetic fields
TL;DR: The linear and nonlinear evolution of the generated primordial fields through the radiation era, including viscous effects are traced, and primordial magnetic fields could strongly influence structure formation, especially on dwarf galaxy scales.

TL;DR: In this paper, the origin and parameters of turbulence and magnetic fields in galaxy clusters were discussed using simple analytical models and magnetohydrodynamic (MHD) simulations, and it was shown that turbulent motions can be maintained in the intracluster gas and its dynamo action can prevent such a decay and amplify a random seed magnetic field by a net factor of typically 104 in 5 Gyr.
Journal ArticleDOI
The origin, evolution and signatures of primordial magnetic fields
TL;DR: In this article, the authors trace the linear and nonlinear evolution of the generated primordial magnetic fields through the radiation era, including viscous effects, and conclude that primordial magnetohydrodynamics could strongly influence structure formation, especially on dwarf galaxy scales.
Journal ArticleDOI
Magnetohydrodynamics in the early universe and the damping of nonlinear Alfvén waves
TL;DR: In this article, the evolution and viscous damping of cosmic magnetic fields in the early universe is analyzed using the fact that the fluid, electromagnetic, and shear viscous energy-momentum tensors are all conformally invariant.
