Where do moving punctures go?
Mark Hannam, Sascha Husa, Niall Ó Murchadha +3
Currently the most popular method to evolve black-hole binaries is the ``moving puncture'' method. It has recently been shown that when puncture initial data for a Schwarzschild bl…
The Einstein constraints: uniqueness and non-uniqueness in the conformal thin sandwich approach
Thomas W. Baumgarte, Niall Ó Murchadha, Harald P. Pfeiffer
We study the appearance of multiple solutions to certain decompositions of Einstein's constraint equations. Pfeiffer and York recently reported the existence of two branches of sol…
Geometry and Regularity of Moving Punctures
Mark Hannam, Sascha Husa, Denis Pollney +2
Significant advances in numerical simulations of black-hole binaries have recently been achieved using the puncture method. We examine how and why this method works by evolving a s…
