Numerical Computation of Black Hole Coalescence

L博士Kidder和S. Teukolsky将进行研究numericalgravitation，并将开发新的算法超级计算机模拟解决方案的爱因斯坦方程。重点是跟踪双黑洞系统的合并和合并过程，并计算由这一过程产生的引力波形。研究人员将应用伪谱拼接的计算技术来解决这个问题。可靠波形的研究是非常及时的。这个问题的理论解决是非常困难的。虽然在这项研究中所使用的技术是新的应用，它已被证明是成功的，在许多其他领域，并显示出很大的承诺，为提高计算效率在这一领域。 正在研究的辐射过程是引力波探测器的主要目标，如LIGO，目前正在建设中。

Drs. L. Kidder and S. Teukolsky will carry out research in numericalgravitation, and will develop new algorithms for supercomputersimulations of solutions to the Einstein Equations. The focus is totrack the coalescence and merger of binary black hole systems and tocalculate the gravitational waveform emitted by such processes. Theinvestigators will apply the computational technique of pseudospectralcollacation to this problem. The study of reliable waveforms is particularly timely.The theoretical solution of this problem is remarkably difficult.While the technique used in this study are new for this application, ithas proven successful in many other areas, and shows much promise forimproving computational efficiency in this area. The radiationprocesses under study are the primary target for gravitational wavedetectors, such as LIGO, currently under construction.
