US-Germany Cooperative Research: On Some Fundamental Issues in the Initial Boundary Value Problem of GR

0307290lehner该奖项支持来自路易斯安那州立大学的PI，博士后和研究生与德国戈姆马克斯普朗克引力物理研究所阿尔伯特爱因斯坦研究所的Helmut Friedrich合作。此次合作的主要目标之一是建立计算模型，以便能够预测由强引力、高动态源（如黑洞和双星脉冲星）产生的引力波。世界各地都有引力波天线的原型，而引力波辐射的复杂性要求用数值方法来解释来自探测器的数据。爱因斯坦方程的数值模拟将使研究人员能够深入探索理论并理解一般系统。美国和德国研究小组的计算专业知识结合起来，将产生一个强大的爱因斯坦方程模拟，这将对引力波的探测和分析具有不可估量的价值。该项目还实现了一个培训目标。该国际项目将允许参与的研究生和博士后从在另一个国家进行研究中受益。他们将接触到一个国际合作的环境，同时也学习重要的新技术技能。

0307290LehnerThis award supports the PI, postdocs, and graduate students from Louisiana State University in a collaboration with Helmut Friedrich of the Albert Einstein Institute at the Max Planck Institute for Gravitation Physics in Golm, Germany. One of the main goals of the collaboration is to produce computational models that will be able to predict the gravitational waves produced by strongly gravitating, highly dynamical sources, such as black holes and binary pulsars. Prototype gravitational wave antennae exist throughout the world, and the complexity of gravitational radiation requires numerical methods to make interpretation of data from the detectors possible. The numerical simulation of Einstein's equations will allow researchers to probe deep into the theory and understand generic systems. The computational expertise of the groups in the US and Germany, when combined, will produce a robust simulation of the Einstein equations, which will be invaluable in the detection and analysis of gravitational waves.The project also fulfills a training objective. The international project will allow graduate and postdoctoral students involved to benefit from performing research in another country. They will be exposed to an international collaborative environment while also learning important new technical skills.
