Feb 17 2015 The SXS collaboration has produced the first computation of black hole binary coalescence that is capable of following the black holes for over 175 orbits until they collide. Previous computations were limited to only a few dozen orbits. The ability to track many orbits is important for testing the post-Newtonian approximation and for producing waveforms that cover the entire range of frequencies that will be seen by LIGO. See the preprint here (http://arxiv.org/abs/1502.04953).
Come, you lost Atoms, to your Centre draw, And be the Eternal Mirror that you saw: Rays that have wander'd into Darkness wide, Return and back into your Sun subside.
From Farid al-Din Attar's twelfth-century masterpiece The Conference of the Birds
The SXS project is a collaborative research effort involving multiple institutions. Our goal is the simulation of black holes and other extreme spacetimes to gain a better understanding of Relativity, and the physics of exotic objects in the distant cosmos.
The SXS project is supported by Canada Research Chairs, CFI, CIfAR, Compute Canada, Max Planck Society, NASA, NSERC, the NSF, Ontario MEDI, the Sherman Fairchild Foundation, and XSEDE.
