INT-0242507LehnerThis award supports a three-year collaborative research project between Professor Luis Lehner (LSU), and Professor Nigel T. Bishop (University of South Africa). The investigators will collaborate on research for the simulation of binary systems containing: [a] black hole and a star and [b] a supermassive black hole and a star . The USA side will contribute with its expertise on the needed simulations and computational facilities while the South African side its expertise on algebraic manipulation. Additionally, both sides have vast knowledge on the formalism and numerical techniques that will be employed in the project. The goal will be to predict the expected gravitational wave emission produced by these systems. These two target systems are prime candidates to produce radiation, of gravitational origin, which highly sensitive detectors could measure (earth-based detectors in system [a], while spaced-based detectors for [b]). The prediction of the expected gravitational waves will be important for their detection and crucial for deciphering the information carried by them. Furthermore, the activities of this project will give new research opportunities to young researchers in both countries (and in particular to two junior investigators in South Africa at historically disadvantaged institutions). The project will introduce a new generation of scientists to multidisciplinary and collaborative research and enhance the participation of the South African partners in leading edge research in gravitational wave physics. This award is co-funded by NSF's Office of International Science and Engineering and by the Stellar Astronomy and Astrophysics Program, Division of Astronomical Sciences, Directorate of Mathematical and Physical Sciences.

INT-0242507LEHNERTHIS奖支持Luis Lehner（LSU）教授和Nigel T. Bishop（南非大学）教授之间的为期三年的合作研究项目。 研究人员将合作研究包含的二进制系统的仿真：[A]黑洞和星星和[B]超级质量的黑洞和一颗星星。美国方面将以其在所需的模拟和计算设施方面的专业知识，而南非方面的代数操纵方面的专业知识。此外，双方都对项目将采用的形式主义和数值技术有广泛的了解。目标是预测这些系统产生的预期重力波排放。这两个目标系统是产生引力起源的辐射的主要候选物，高度敏感的检测器可以测量（基于地球的检测器[A]，而[B]的基于间隔的检测器）。预期重力波的预测对于它们的检测至关重要，对于破译它们所携带的信息至关重要。此外，该项目的活动将为两国的年轻研究人员提供新的研究机会（尤其是南非的两名初级调查员，历史上处于弱势阶层的机构）。该项目将介绍新一代的科学家进行多学科和合作研究，并增强南非合作伙伴参与引力波物理学领先研究。该奖项由NSF国际科学与工程办公室以及恒星天文学和天体物理学计划，天文学科学部，数学和物理科学局共同资助。
