| A Gauge-invariant Analysis of Magnetic Fields in General Relativistic Cosmology (2007) | |||||||||||||
Abstract | |||||||||||||
| We provide a fully general-relativistic treatment of cosmological perturbations in a universe permeated by a large-scale primordial magnetic field using the Ellis-Bruni gauge-invariant formalism. The exact non-linear equations for general relativistic magnetohydrodynamic evolution are derived. A number of applications are made: the behaviour of small perturbations to Friedmann universes are studied; a comparison is made with earlier Newtonian treatments of cosmological perturbations and some effects of inflationary expansion are examined. 1 | |||||||||||||
