US-South Africa Cooperative Research: Characteristic Evolution of Black Hole-Star Binary Systems

该奖项支持路易斯·雷纳教授（路易斯安那州立大学）和奈杰尔·t·毕晓普教授（南非大学）之间为期三年的合作研究项目。研究人员将合作研究双星系统的模拟：[a]黑洞和一颗恒星，[b]超大质量黑洞和一颗恒星。美国方面将提供其在所需的模拟和计算设施方面的专门知识，而南非方面将提供其在代数操作方面的专门知识。此外，双方在项目中将使用的形式化和数值技术方面都有丰富的知识。目标将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，高灵敏度的探测器可以测量（系统[a]中的地面探测器，而[b]中的空间探测器）。对预期引力波的预测对于探测引力波非常重要，对于破译引力波所携带的信息也至关重要。此外，这个项目的活动将给两国的年轻研究人员提供新的研究机会（特别是给南非历史上处于不利地位的机构的两名初级研究人员）。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对引力波物理学前沿研究的参与。该奖项由美国国家科学基金会国际科学与工程办公室、恒星天文学和天体物理学项目、天文科学部、数学和物理科学理事会共同资助。

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.
