Geodesics in nonexpanding impulsive gravitational waves with Λ, part I

Sämann, C., Steinbauer, R., Lecke1, A., Podolský, J.

We investigate the geodesics in the entire class of nonexpanding impulsive
gravitational waves propagating in an (anti-)de Sitter universe using the distributional
form of the metric. Employing a five-dimensional embedding
formalism and a general regularisation technique, we prove the existence and
uniqueness of the geodesics crossing the wave impulse, leading to a completeness
result. We also derive the explicit form of the geodesics, thereby
confirming previous results derived in a heuristic approach.
