Gravitational wave extraction based on Cauchy-characteristic extraction and characteristic evolution

General Relativity and Quantum Cosmology 2009-11-11 v2

Abstract

We implement a code to find the gravitational news at future null infinity by using data from a Cauchy code as boundary data for a characteristic code. This technique of Cauchy-characteristic Extraction (CCE) allows for the unambiguous extraction of gravitational waves from numerical simulations.
