Scattering on Quasi-Spherical Black-Holes: Features and Beyond

Recent developments in the gravitational waves interferometry require more pertinent theoretical models of generation and propagation. Untouched possible mechanisms spin-2 spacetime perturbations production, we will consider their subsequent scattering on other black holes (BHs). Specifically, a generalization Regge-Wheeler-Zerilli equations for case distorted BHs (BHs surrounded with matter) Minkowski Anti-de Sitter spacetimes, metric potential which obeys Liouville equation. We establish significant differences characteristics different spins angular momenta, including waves, caused by losing spherical symmetry propagation background. In particular, demonstrate strong impact background geometry deformation grey-body factors, hence absorption cross-sections explore issue stability upon changing degree parameters.
