Gravitational waves from inclined orbits around Kerr black holes
Yi-Han Huang, Sen Guo, Yu Liang +2
Extreme mass ratio inspirals on generic inclined orbits provide a critical dynamical probe of strong field gravity, as they uniquely break the severe parameter degeneracies inheren…
Influence of quantum decoherence on black hole shadow visibility and time domain echoes
