Freely falling bodies in a standing-wave spacetime

Freely falling bodies in a standing-wave spacetime

We study the motion of free masses subject to the influence of standing gravitational waves in the polarized Gowdy cosmology with a three-torus topology. We show that antinodes attract freely falling particles and we trace the velocity memory effect.
