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…

Gravitational Memory Effect in the Massless Vector Field
Pouneh Safarzadeh Ilkhchi, Amin Rezaei Akbarieh, Shaoqi Hou
We analyze the infrared structure and memory effects of a massless vector tensor theory with non minimal curvature coupling in asymptotically flat spacetimes. Using Bondi Sachs exp…
