Coalescence of Binary Black Holes and Neutron Stars: Computational Contributions to LIGO

*9800737Teukolsky康奈尔研究小组将对双星黑洞的合并进行全三维模拟。在成功模拟紧凑的二进制合并之前，重要的理论和算法问题仍有待解决。康奈尔大学的团队预计将在未来三年内克服其中的大部分挑战。他们还将对双星中子星的合并进行完全相对论模拟。这些模拟将共享为合并黑洞而开发的大部分代码。来自黑洞和中子星双星的最终俯冲和合并的引力波形式是LIGO和其他引力波干涉仪的主要目标。这些波形只能通过大规模的数值计算来预测。如果这些模拟波形要及时提供给LIGO社区，现在必须继续进行大量的计算工作。康奈尔大学的研究小组将与其他研究人员合作解决这些重要问题。

***9800737TeukolskyThe Cornell group will carry out fully three-dimensional simulations of the coalescence of binary black holes. Important theoretical and algorithmic issues remain to be solved before successful simulations of compact binary mergers can be achieved. The Cornell group expects to overcome most of these challenges in the next three years. They will also perform fully relativistic simulations of mergers of binary neutron stars. These simulations will share much of the code developed for merging black holes.Gravitational wave forms from the final plunge and coalescence of black-hole and neutron-star binaries are primary targets for LIGO and other gravitational wave interferometers. These wave forms can only be predicted by large-scale numerical computations. If such simulated wave forms are to be made available to the LIGO community in a timely fashion, a significant effort to compute them must be continued now. The Cornell group will collaborate with other researchers to tackle these important problems.***
