中文摘要
该项目继续开发碰撞黑洞的3D数值模拟和将合并的黑洞近似描述为单个扭曲的黑洞(接近极限近似)之间的接口。界面的成功开发将使黑洞碰撞的演化从下降阶段持续到最后的环化阶段。对这两个阶段的模拟将使人们能够估计波形和辐射角动量和能量。这些估计将是产生对引力波探测器有用的信息的有用的第一步,并可用于交叉检查使用不同3D代码和接口的类似研究。
英文摘要
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.
