More quickly rotating black holes

The SXS collaboration can now simulate binaries containing black holes that spin at a rate of 99.4% of their maximum theoretical value, the fastest spins ever simulated.  The technical improvements allowing such large spins are reported here (http://arxiv.org/abs/1412.1803and an investigation of the maximum spin during binary coalescence can be found here (http://arxiv.org/abs/1411.7297)

Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run twice as fast as that.

About SXS

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.
