Partially locally rotationally symmetric perfect fluid cosmologies
Nazeem Mustapha, George F R Ellis, Henk van Elst +1
We show that there are no new consistent cosmological perfect fluid solutions when in an open neighbourhood of an event the fluid kinematical variables and the electric…
Parametric Excitation of Alfven Waves by Gravitational Radiation
M. Servin, G. Brodin, M. Bradley +1
We consider the parametric excitation of Alfven waves by gravitational radiation propagating on a Minkowski background, parallel to an external magnetic field. As a starting point,…
The Wahlquist metric cannot describe an isolated rotating body
Michael Bradley, Gyula Fodor, Mattias Marklund +1
It is proven that the Wahlquist perfect fluid space-time cannot be smoothly joined to an exterior asymptotically flat vacuum region. The proof uses a power series expansion in the…
Radio wave emissions due to gravitational radiation
Mattias Marklund, Gert Brodin, Peter Dunsby
We consider the interaction of a weak gravitational wave with electromagnetic fields in a thin plasma on a Minkowski background spacetime using the 1+3 orthonormal frame formalism.…
