拉扎里尼描述：该奖项支持一项名为从激光干涉数据中提取螺旋致密双星引力波信号的美印合作研究项目。美国加州理工学院的阿尔伯特·拉扎里尼和宾夕法尼亚州立大学的李·芬恩将在浦那的大学间天文学和天体物理中心(IUCAA)与Sanjeev Dhurandhar和他的团队中的两名年轻科学家合作。这项研究的目的是通过提高探测引力波的效率和概率来促进引力波物理学的发展。第一个任务是设计计算高效的信号提取技术来检测激励二进制信号；第二个任务是通过分析如何使用检测器网络识别这些信号来增加波检测的可能性。范围：印度的合作者拥有互补的技能和专业知识，以确保成功的合作。理论分析、算法设计和仿真是它们的重要组成部分。Dhurandhar教授和他领导的IUCAA小组因从探测器数据中提取激励二进制信号的理论工作而在国际上获得认可。来自印度的两名年轻科学家的参与可能会对美国在引力波探测方面的努力做出宝贵的贡献。美国PI是这一领域的领先研究人员。新成立的引力物理中心(CGWP)致力于引力波天体物理的物理学和现象学研究，并由物理学前沿中心计划资助。CGWP将接待印度研究人员的访问。

0138459Lazzarini Description: This award supports a US-India cooperative research project entitled Extracting Gravitational Wave Signals of Inspiraling Compact Binary Stars from Laser Interferometric Data. US PIs Albert Lazzarini, California Institute of Technology and Lee Finn, Pennsylvania State University will collaborate with Sanjeev Dhurandhar and two young scientists from his group at the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune. The aim of the research is to advance gravitational wave physics by raising the efficiency and probability of detecting gravitational waves. The first task is to devise computationally efficient signal extraction techniques for detecting inspiraling binary signals; the second is to increase the likelihood of wave detection by analyzing how these signals can be identified using a network of detectors. Scope: The Indian collaborators have complementary skills and the expertise to ensure a successful collaboration. Theoretical analysis, algorithm design, and simulations are the vital components from their side. Professor Dhurandhar and the IUCAA group, which he heads, is internationally recognized for theoretical work on extraction of inspiraling binary signals from detector data. The participation of two young scientists from India has the potential to be a valuable contribution to the US effort in gravitational wave detection. The US PIs are leading researchers in this field. The newly established Center for Gravitational Physics (CGWP) is dedicated to the physics and phenomenology of gravitational wave astrophysics and funded under the Physics Frontier Center Program. The CGWP will host the visits of the Indian researchers.
