Self force on a scalar charge in Kerr spacetime: inclined circular orbits
Niels Warburton
Accurately modeling astrophysical extreme-mass-ratio-insprials requires calculating the gravitational self-force for orbits in Kerr spacetime. The necessary calculation techniques…
Tidal invariants for compact binaries on quasi-circular orbits
Sam R. Dolan, Patrick Nolan, Adrian C. Ottewill +2
We extend the gravitational self-force approach to encompass `self-interaction' tidal effects for a compact body of mass on a quasi-circular orbit around a black hole of mass $…
Propagation of Test Particles and Scalar Fields on a Class of Wormhole Space-Times
Peter Taylor
In this paper, we consider the problem of test particles and test scalar fields propagating on the background of a class of wormhole space-times. For test particles, we solve for a…
Gravitational Self-Force Correction to the Innermost Stable Circular Equatorial Orbit of a Kerr Black Hole
Soichiro Isoyama, Leor Barack, Sam R. Dolan +5
For a self-gravitating particle of mass μin orbit around a Kerr black hole of mass M >> μ, we compute the O(μ/M) shift in the frequency of the innermost stable circular equatorial…
Generating a Cosmological Constant with Gravitational Waves
C. Barrabès, P. A. Hogan
A technique is given to derive the well known Bell-Szekeres solution of the Einstein-Maxwell vacuum field equations describing the space-time and the Maxwell field following the he…
Self-force via Green functions and worldline integration
Barry Wardell, Chad R. Galley, Anil Zenginoglu +3
A compact object moving in curved spacetime interacts with its own gravitational field. This leads to both dissipative and conservative corrections to the motion, which can be inte…
