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

该奖项支持路易斯安那州立大学与德国格勒姆马克斯·普朗克引力物理研究所阿尔伯特·爱因斯坦研究所的赫尔穆特·弗里德里希合作，为PI、博士后和研究生提供支持。合作的主要目标之一是建立计算模型，能够预测由强引力、高动力学来源产生的引力波，例如黑洞和双星脉冲星。引力波天线的原型存在于世界各地，而引力辐射的复杂性需要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了解一般系统。美国和德国团队的计算专长结合在一起，将产生对爱因斯坦方程的强大模拟，这将在引力波的探测和分析中具有无价的价值。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。他们将接触到国际协作环境，同时还将学习重要的新技术技能。

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.
