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.

0307290LEHNERTHIS奖与路易斯安那州立大学的PI，PostDocs和研究生与德国Max Planck重力学院的Albert Einstein Institute的Helmut Friedrich合作。 该协作的主要目标之一是产生计算模型，以预测通过强烈引力，高度动态的来源（例如黑洞和二进制脉冲星）产生的重力波。 全世界都存在原型引力波触角，重力辐射的复杂性需要数值方法来解释从检测器中解释数据。 爱因斯坦方程的数值模拟将使研究人员能够深入研究理论并了解通用系统。 在美国和德国组合组合的群体的计算专业知识将对爱因斯坦方程进行稳健的模拟，这将在引力波的检测和分析中无价。该项目还实现了训练目标。 国际项目将允许参与研究生和博士后学生从另一个国家进行研究。 他们将接触到国际协作环境，同时还学习重要的新技术技能。
