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-0242507 Lehner该奖项支持Luis Lehner教授（路易斯安那州立大学）和奈杰尔T教授之间为期三年的合作研究项目。毕晓普（南非大学）。 研究人员将合作研究二元系统的模拟：[a]黑洞和一颗星星，[B]超大质量黑洞和一颗星星。美国方面将提供所需模拟和计算设施方面的专业知识，而南非方面将提供代数运算方面的专业知识。此外，双方都对项目中将采用的形式主义和数值技术有着丰富的知识。目标是预测这些系统产生的预期引力波发射。这两个目标系统是产生引力源辐射的主要候选者，高灵敏度探测器可以对其进行测量（系统[a]中的地球探测器，而[B]中的空间探测器）。对预期引力波的预测对于它们的探测非常重要，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（特别是南非历史上处于不利地位的机构的两名初级研究人员）提供新的研究机会。该项目将为多学科和合作研究引入新一代科学家，并加强南非合作伙伴在引力波物理前沿研究中的参与。该奖项由NSF的国际科学与工程办公室以及数学和物理科学理事会天文科学部恒星天文学和天体物理学计划共同资助。
