Gravitational self-torque and spin precession in compact binaries
Sam R. Dolan, Niels Warburton, Abraham I. Harte +3
We calculate the effect of self-interaction on the "geodetic" spin precession of a compact body in a strong-field orbit around a black hole. Specifically, we consider the spin prec…
Gravitational self-force from radiation-gauge metric perturbations
Adam Pound, Cesar Merlin, Leor Barack
Calculations of the gravitational self-force (GSF) in curved spacetime require as input the metric perturbation in a sufficiently regular gauge. A basic challenge in the program to…
Frequency-domain algorithm for the Lorenz-gauge gravitational self-force
Sarp Akcay, Niels Warburton, Leor Barack
State-of-the-art computations of the gravitational self-force (GSF) on massive particles in black hole spacetimes involve numerical evolution of the metric perturbation equations i…
Isofrequency pairing of geodesic orbits in Kerr geometry
Niels Warburton, Leor Barack, Norichika Sago
Bound geodesic orbits around a Kerr black hole can be parametrized by three constants of the motion: the (specific) orbital energy, angular momentum and Carter constant. Genericall…
