@article{Campanelli2006AccurateEO, title={Accurate evolutions of orbiting black-hole binaries without excision.}, author={Manuela Campanelli and Carlos O. Lousto and Pedro Marronetti and Yosef Zlochower}, journal={Physical review letters}, year={2006}, volume={96 11}, pages={ 111101 } }

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 lapse, is nonsingular at the start of the evolution and remains nonsingular and stable provided that a good choice is made for the gauge. As a…
