A Class of Collisions of Plane Impulsive Light--Like Signals in General Relativity
C. Barrabes, P. A. Hogan
We present a systematic study of collisions of homogeneous, plane--fronted, impulsive light--like signals which do not interact after head--on collision. For the head--on collision…

The Aichelburg-Sexl Boost of Domain-Walls and Cosmic Strings
C. Barrabes, P. A. Hogan, W. Israel
We consider the application of the Aichelburg-Sexl boost to plane and line distributions of matter. Our analysis shows that for a domain wall the space-time after the boost is flat…

Gravitational Wave Propagation in Isotropic Cosmologies
P. A. Hogan, E. M. O'Shea
We study the propagation of gravitational waves carrying arbitrary information through isotropic cosmologies. The waves are modelled as small perturbations of the background Robert…
