Gravitational wave amplification of seed magnetic fields
C. G. Tsagas, P. K. S. Dunsby, M. Marklund
We discuss how gravitational waves could amplify seed magnetic fields to strengths capable of supporting the galactic dynamo. We consider the interaction of a weak magnetic field w…
(1+3) Covariant Dynamics of Scalar Perturbations in Braneworlds
Bernard Leong, Peter Dunsby, Anthony Challinor +1
We discuss the dynamics of linear, scalar perturbations in an almost Friedmann-Robertson-Walker braneworld cosmology of Randall-Sundrum type II using the 1+3 covariant approach. We…
Plane fronted parallel waves in a warm two-component plasma
Gert Brodin, Mattias Marklund, Peter Dunsby
A general system of equations is derived, using the 1+3 orthonormal tetrad formalism, describing the influence of a plane-fronted-parallel gravitational wave on a warm relativistic…
Bounce behaviour in Kantowski-Sachs and Bianchi Cosmologies
Deon Solomons, Peter Dunsby, George Ellis
Many cosmological scenarios envisage either a bounce of the universe at early times, or collapse of matter locally to form a black hole which re-expands into a new expanding univer…
Exact Inflation Braneworlds
Deon Solomons, Peter Dunsby, George Ellis
In Randall-Sundrum type braneworld cosmologies, the dynamical equations on the three-brane differ from the general relativity equations by terms that carry the effects of embedding…
