Charged Black-Hole Binary Evolution at Second Post-Newtonian Order

Andrea Placidi, Elisa Grilli, Marta Orselli +3

We study the dynamics of electrically charged black-hole binaries and their gravitational-wave emission during the inspiral phase. Within the post-Newtonian framework, we derive th…

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…

Charged Binaries in Gravitational Tides

Elisa Grilli, Marta Orselli, David Pereñiguez +1

Next-generation low-frequency interferometers are expected to detect binary systems near supermassive black holes, where tidal effects can alter significantly the motion of the bin…

Direct current memory effects in effective-one-body waveform models

Elisa Grilli, Andrea Placidi, Simone Albanesi +2

The direct current (DC) memory is a non-oscillatory, hereditary component of the gravitational wave (GW) signal that represents one of the most peculiar manifestations of the nonli…
