Generating Electromagnetic Waves from Gravity Waves in Cosmology
P. A. Hogan, S. O'Farrell
Examples of test electromagnetic waves on a Friedmann-Lemaitre-Robertson-Walker(FLRW) background are constructed from explicit perturbations of the FLRW space-times describing grav…

Colliding Plane Impulsive Gravitational Waves
C. Barrabès, G. F. Bressange, P. A. Hogan
When two non-interacting plane impulsive gravitational waves undergo a head-on collision, the vacuum interaction region between the waves after the collision contains backscattered…
