The behaviour of geodesics in constant-curvature spacetimes with expanding impulsive gravitational waves

Švarc R.; Podolský J.

Motion of free test particles in spacetimes of constant curvature with an expanding
impulsive gravitational wave is completely described. Explicit formulae which identify the
particle positions and velocities “in front of” and “behind” the impulse are derived for a general
impulse of this type. As a particular example, the effect of spherical impulsive wave generated
by a snapped cosmic string is analyzed and visualized.
