Inspiral of Equal-Mass Black Holes with Spin Anti-Aligned to the Orbital Angular Momentum and of Magnitude 0.95

The spins have magnitude 0.95, are parallel to each other, but are anti-aligned with the orbital angular momentum. This simulation is described in a publication in Phys. Rev. D., in press. The paper can also be accesed at arXiv:1010.2777.

Movie displaying the evolution of the scalar curvature, R, on the apparent horizons


Note that aside from corrections that become important only near the time of merger, the spin function χ and scalar curvature R should agree well with -2Bnn and -2Enn, respectively, where Bnn and Enn are the horizon vorticity and tendicity, respectively.

Four Areas of Science


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.

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.
