Abstract: We present a method for extracting gravitational radiation from a three-dimensional numerical relativity simulation and, using the extracted data, to provide outer boundary conditions. The method treats dynamical gravitational variables as nonspherical perturbations of Schwarzschild geometry. We discuss a code which implements this method and present results of tests which have been performed with a three-dimensional numerical relativity code.

A Proximity Measure using Blink Model
TL;DR: It is demonstrated that this measure is more consistent with human intuition than competitors and achieves accuracies that are 14-35% above the best accuracy for each graph of all predictors reported in the 2007 Liben-Nowell and Kleinberg survey.

Stability of a Schwarzschild Singularity
TL;DR: In this article, it was shown that a Schwarzschild singularity, spherically symmetrical and endowed with mass, will undergo small vibrations about the spherical form and therefore remain stable if subjected to a small nonspherical perturbation.

Effective potential for even parity Regge-Wheeler gravitational perturbation equations
TL;DR: In this article, the Schrodinger-type equation for odd-parity perturbations on a background geometry has been extended to the even-PARITY perturbation, which should greatly simplify the analysis for calculations of gravitational radiation from stars and from objects falling into black holes.

Gravitational perturbations of spherically symmetric systems. I. The exterior problem
TL;DR: Gravitational perturbations of the Schwarzschild metric are treated from a point of view which is adapted, in a natural way, to the gauge group of the perturbed Einstein equations as discussed by the authors.

Towards a singularity-proof scheme in numerical relativity.
TL;DR: A scheme which excises a region inside an apparent horizon containing the singularity through the use of a horizon-locking coordinate and a finite differencing which respects the causal structure of the spacetime.
