The Magnetized Universe
Cosmology, high-energy physics and astrophysics are converging on the study of large-scale magnetic fields. While the experimental evidence for the existence of large-scale magnetization in galaxies, clusters and superclusters is rather compelling, the origin of the phenomenon remains puzzling especially in light of the most recent observations. The purpose of the present review is to describe ...
متن کاملGalaxy formation and cosmic-ray acceleration in a magnetized universe
We study the linear magneto-hydrodynamical behaviour of a Newtonian cosmology with a viscous magnetized fluid of finite conductivity and generalise the Jeans instability criterion. The presence of the field favors the anisotropic collapse of the fluid, which in turn leads to further magnetic amplification and to an enhanced current-sheet formation in the plane normal to the ambient magnetic fie...

متن کاملOn the Formation of Plasma Structures in our Magnetized Dusty Universe
Our universe is magnetized and its constituents are the electrons, anti-electrons (positrons), ions and dust particles. Our objective here is to discuss the formation of large scale plasma structures based on a model associated with the Jeans instability in a self-gravitating multi-component fully ionized magnetoplasma. Assuming that the plasma particles are magnetized and charged dust grains f...
متن کاملPlane-symmetric inhomogeneous magnetized viscous fluid universe with a variable Λ
The behavior of magnetic field in plane symmetric inhomogeneous cosmological models for bulk viscous distribution is investigated. The coefficient of bulk viscosity is assumed to be a power function of mass density (ξ = ξ0ρ n). The values of cosmological constant for these models are found to be small and positive which are supported by the results from recent supernovae Ia observations. Some p...
