Tidal perturbations of an extreme mass ratio inspiral around a Kerr black hole
Marta Cocco, Gianluca Grignani, Troels Harmark +3
We determine the metric of a Kerr black hole subject to external tidal fields using metric reconstruction techniques. Working within the Newman-Penrose formalism, we solve the Teuk…

Observable signature of magnetic tidal coupling in hierarchical triple systems
Marta Cocco, Gianluca Grignani, Troels Harmark +3
We study hierarchical triple systems formed by a compact binary orbiting a supermassive black hole (SMBH), focusing on the role of relativistic magnetic tidal interactions. Extendi…

Strong-gravity precession resonances for binary systems orbiting a Schwarzschild black hole
Marta Cocco, Gianluca Grignani, Troels Harmark +2
Binary systems of compact objects in close orbit around a supermassive black hole (SMBH) may form in galactic nuclei, providing a unique environment to probe strong-gravity tidal e…
