We present a new algorithm for evolving orbiting black-hole binaries that does not require excision or a corotating shift. Our algorithm is based on a novel technique to handle the singular puncture conformal factor. This system, based on the Baumgarte-Shapiro-Shibata-Nakamura formulation of Einstein's equations, when used with a "precollapsed" initial(More)
We discuss results that have been obtained from the implementation of the initial round of testbeds for numerical relativity which was proposed in the first paper of the Apples with Apples Alliance. We present benchmark results for various codes which provide templates for analyzing the testbeds and to draw conclusions about various features of the codes.(More)
of numerical relativity groups is generating a large catalog of waveforms, and a dictionary of the information in the waveforms (13). These waveforms will be observed by the Laser Interferometer Gravitational Wave Observatory (LIGO), with interferometers in Livingston, Louisiana, and Hanford, Washington, and by LIGO's international partners: the Virgo(More)
