Charged multifluids in general relativity
Mattias Marklund, Peter K. S. Dunsby, Gerold Betschart +2
The exact 1+3 covariant dynamical fluid equations for a multi-component plasma, together with Maxwell's equations are presented in such a way as to make them suitable for a gauge-i…
A relativistic approach to nonlinear peculiar velocities and the Zeldovich approximation
George F. R. Ellis, Christos G. Tsagas
We study the peculiar motion of non-relativistic matter in a fully covariant way. The exact nonlinear equations are derived and then applied to the case of pressure-free matter, mo…
CMB limits on large-scale magnetic fields in an inhomogeneous universe
C. A. Clarkson, A. A. Coley, R. Maartens +1
We use the cosmic microwave background temperature anisotropy to place limits on large-scale magnetic fields in an inhomogeneous (perturbed Friedmann) universe. If no assumptions a…
Gravitational waves and cosmic magnetism; a cosmological approach
Christos G. Tsagas
We present the formalism for the covariant treatment of gravitational radiation in a magnetized environment and discuss the implications of the field for gravity waves in the cosmo…
Cosmological Perturbations
Christos G. Tsagas
The aim of these lecture notes is to familiarize graduate students and beginning postgraduates with the basic ideas of linear cosmological perturbation theory and of structure form…
