Contribution
It introduces a method to compute momentum transfer by gravitational waves with various wavefront shapes in cosmological models.
Findings
Momentum transfer is well-defined for toroidal wavefronts.
Results reduce to spherical wavefront case under specific conditions.
Operational procedure effectively computes gravitational wave momentum.
Abstract
We calculate momentum imparted by colliding gravitational waves in a closed Friedmann Robertson-Walker background and also by gravitational waves with toroidal wavefronts using an operational procedure. The results obtained for toroidal wavefronts are well behaved and reduce to the spherical wavefronts for a special choice.
