Pfeiffer, and James M. Bardeen<br/>We generalize Bowen-York black hole initial data to hyperboloidal constant mean curvature slices which extend to future null infinity. We solve this initial value problem numerically for several cases, including unequal mass binary black holes with spins and boosts. The singularity at null infinity ...<br/>[Phys. Rev.

The small black hole is either rotating or nonrotating, and it moves on a circular orbit in the equa...<br/>[Phys. Rev.
