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…
Collision of Shock Waves in Einstein-Maxwell Theory with a Cosmological Constant: A Special Solution
C. Barrabès, P. A. Hogan
Post-collision space-times of the Cartesian product form M'xM'', where M' and M'' are two-dimensional manifolds, are known with M' and M'' having constant curvatures of equal and o…
Applying the effective-source approach to frequency-domain self-force calculations
Niels Warburton, Barry Wardell
The equations of motion of a point particle interacting with its own field are defined in terms of a certain regularized self-field. Two of the leading methods for computing this r…
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…
Error-analysis and comparison to analytical models of numerical waveforms produced by the NRAR Collaboration
Ian Hinder, Alessandra Buonanno, Michael Boyle +53
The Numerical-Relativity-Analytical-Relativity (NRAR) collaboration is a joint effort between members of the numerical relativity, analytical relativity and gravitational-wave data…
Scalar self-force for eccentric orbits around a Schwarzschild black hole
Ian Vega, Barry Wardell, Peter Diener +2
We revisit the problem of computing the self-force on a scalar charge moving along an eccentric geodesic orbit around a Schwarzschild black hole. This work extends previous scalar…
