Gravitational Lensing of Gravitational Waves: Spin-wave Optics through Black Hole Scattering
Zhao Li, Shaoqi Hou, Wen Zhao
Gravitational-wave (GW) scattering in strong gravitational fields is a central problem in GW lensing. Yet, conventional treatments based on asymptotic expansions suffer from diverg…
