Survey of aligned-spin binary black holes

The SXS collaboration has produced a catalog of about 90 simulations of binary black holes with spins aligned with the orbital angular momentum.  We sample systems with both spins co-rotating, one co-rotating and one counter-rotating, or both counter-rotating.  We compare these simulations with several waveform models in use by LIGO, and find generally excellent agreement.  The papers can be accessed arXiv:1512.06800  and arXiv:1601.05396.

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.
