Generic effective sources for first-order in mass-ratio gravitational self-force calculations in Schwarzschild spacetime
Chao Zhang, Rong-gen Cai, Guoyang Fu +3
The numerical calculation of gravitational self-force in extreme mass ratio inspiral systems is fundamentally challenging due to the singular nature of point-particle sources. To o…
