@article{Hopper2015FastSS, title={Fast spectral source integration in black hole perturbation calculations}, author={S. Hopper and Erik Forseth and Thomas Osburn and C. Evans}, journal={Physical Review D}, year={2015}, volume={92}, pages={044048} }

This paper presents a new technique for achieving spectral accuracy and fast computational performance in a class of black hole perturbation and gravitational self-force calculations involving extreme mass ratios and generic orbits. Called \emph{spectral source integration} (SSI), this method should see widespread future use in problems that entail (i) point-particle description of the small compact object, (ii) frequency domain decomposition, and (iii) use of the background eccentric geodesic… CONTINUE READING
