An interpretation of spacetimes with expanding impulsive gravitational waves generated by snapped cosmic strings
David Kofron, Michal Karamazov, Robert Svarc
The geometric properties of spacetimes representing expanding impulsive gravitational waves, propagating on a flat background and generated by snapped cosmic strings, are studied.…

Gyratonic pp-waves and their impulsive limit
Jiri Podolsky, Roland Steinbauer, Robert Svarc
We investigate a class of gravitational pp-waves which represent the exterior vacuum field of spinning particles moving with the speed of light. Such exact spacetimes are described…

Refraction of geodesics by impulsive spherical gravitational waves in constant-curvature spacetimes with a cosmological constant
Jiri Podolsky, Robert Svarc
We investigate motion of test particles in exact spacetimes with an expanding impulsive gravitational wave which propagates in Minkowski, de Sitter or anti-de Sitter universe. Usin…
