Computational Relativity

将启动一项新的计算引力研究计划。塞德尔博士的团队将使用超级计算机来研究描述轴对称黑洞时空的爱因斯坦方程。这个小组已经开发了一个数值代码来求解这些旋转黑洞的方程，并将用于研究扭曲、旋转的黑洞和碰撞中的黑洞的演化。我们将计算这些黑洞发出的引力辐射的波形。这些时空中的黑洞视界也将被研究。这项工作将带来对黑洞的更好理解，黑洞将是引力波的重要来源，正在开发的新一代波探测器(LIGO和Virgo)可能会观察到这种引力波。这项工作对于理解旋转黑洞的非线性动力学将特别重要，因为以前从未详细研究过。这项轴对称工作也将为未来将进行的全3D模拟提供一个重要的试验台。

A new program of research in computational gravitation will be initiated. Dr. Seidel's group will use supercomputers to study the Einstein equations describing axisymmetric black hole spacetimes. A numerical code to solve these equations for rotating black holes has been developed by this group, and will be used to study the evolution of distorted, rotating black holes, and black holes in collision. Waveforms of gravitational radiation emitted by these black holes will be calculated. The black hole horizons in these spacetimes will also be studied. This work will lead to a better understanding of black holes, which will be an important source of gravitational waves that may be observable by a new generation of wave detectors (LIGO and VIRGO) under development. This work will be particularly important in understanding the nonlinear dynamics of rotating black holes, which have never been studied before in detail. This axisymmetric work will also provide an important testbed for full 3D simulations that will be performed in the future.
