This project continues the development of an interface between 3D numerical simulations of colliding black holes and an approximate description of the merging black holes as a single distorted black hole (close limit approximation). The successful development of the interface would allow the evolution of the black hole collision to continue through the plunge phase through the final ringdown phase.The simulation of the two stages would allow estimates of the waveform and radiated angular momentum and energy to be made. These estimates would represent a useful first step in producing information useful to gravitational wave detectors and could be used to cross-check similar studies using different 3D codes and interfaces.

该项目继续开发碰撞黑洞的 3D 数值模拟与合并黑洞作为单个扭曲黑洞的近似描述（接近极限近似）之间的接口。 该接口的成功开发将使黑洞碰撞的演化能够继续从暴跌阶段一直到最终的衰荡阶段。对这两个阶段的模拟将允许对波形以及辐射角动量和能量进行估计。 这些估计将代表产生对引力波探测器有用的信息的有用的第一步，并且可用于交叉检查使用不同 3D 代码和接口的类似研究。
