Geodesic congruences, impulsive gravitational waves and gravitational memory
arXiv:1808.04886 · doi:10.1103/PhysRevD.99.024031
Abstract
In this paper we introduce a new approach to the study of the effects that an impulsive wave, containing a mixture of material sources and gravitational waves, has on a geodesic congruence that traverses it. We find that the effect of the wave on the congruence is a discontinuity in the B-tensor of the congruence. Our results thus provide a detector independent and covariant characterization of gravitational memory.
