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.

0307290Lehner该奖项与德国戈尔姆马克斯·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，支持路易斯安那州立大学的 PI、博士后和研究生。 此次合作的主要目标之一是建立计算模型，能够预测强引力、高动态源（例如黑洞和双脉冲星）产生的引力波。 世界各地都存在引力波天线原型，而引力辐射的复杂性需要数值方法来解释探测器的数据。 爱因斯坦方程的数值模拟将使研究人员能够深入探讨理论并理解通用系统。 美国和德国研究小组的计算专业知识相结合，将产生对爱因斯坦方程的强大模拟，这对于引力波的探测和分析将具有无价的价值。该项目还实现了培训目标。 该国际项目将使参与其中的研究生和博士后学生从在另一个国家进行的研究中受益。 他们将接触国际协作环境，同时学习重要的新技术技能。
