Dissection of a merger-ringdown waveform in the small-mass-ratio limit
Patrick Bourg, Lorenzo Küchler, Benjamin Leather +6
Work over the past two decades has unveiled the rich phenomenology of black hole binary mergers and subsequent ringdowns, involving a tapestry of quasinormal modes (QNMs), nonlinea…

Gravitational memory: new results from post-Newtonian and self-force theory
Kevin Cunningham, Chris Kavanagh, Adam Pound +3
We compute the (displacement) gravitational wave memory due to a quasicircular inspiral of two black holes using a variety of perturbative techniques. Within post-Newtonian theory,…

Adiabatic inspirals under electromagnetic radiation reaction on Kerr spacetime
Ethan J German, Kevin Cunningham, Visakan Balakumar +2
A compact body in orbit about a black hole loses orbital energy and angular momentum through radiation-reaction processes, inspiralling towards the black hole until a final plunge.…
