This award provides partial support to enable the collaboration between scientists and students at the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in Pune, India and scientists and students at Washington State University (WSU) and the California Institute of Technology (Caltech) on data analysis for the Laser Interferometer Gravitational-wave Observatory (LIGO). The particular focus will be to develop tools and methods to search for a background of gravitational waves that might arise from the superposition of many astronomical gravitational wave sources that are too weak to detect individually. During their visits to the US, the IUCAA scientists (two faculty members and a graduate student) will provide tutorials to their US counterparts on relevant detection methods used for the cosmic microwave background and radio astronomy. In turn, the US students and faculty will train the IUCAA group in signal simulation techniques. This exchange of information will enable each group to maximize its effectiveness in the project at their respective home institutions while continuing the collaboration via internet telephony. While in the US, the IUCAA group will increase their visibility within the LIGO Scientific Collaboration by attending collaboration meetings. This award is supported by the Division of Physics and the Office of International Science and Engineering.

该奖项提供了部分支持，以在浦那，印度，印度浦那大学天文学与天体物理学中心（IUCAA）以及华盛顿州立大学（WSU）和加利福尼亚州技术研究所（Caltech）在激光干涉仪干涉仪干涉仪层次 - 层次波动仪（LIGO）的数据分析上的科学家与学生之间的合作。特别的重点是开发工具和方法，以寻找由许多天文学重力源的叠加引起的引力波的背景，这些引力源太弱而无法单独检测。在访问美国时，IUCAA科学家（两名教职员工和一名研究生）将以用于宇宙微波背景和射电天文学的相关检测方法为美国同行提供教程。反过来，美国的学生和教职员工将培训IUCAA小组的信号模拟技术。这种信息交换将使每个小组在通过互联网电话继续协作的同时，在各自的家庭机构中最大化其在项目中的有效性。在美国，IUCAA集团将通过参加合作会议来提高他们在Ligo科学合作中的知名度。该奖项得到了物理部和国际科学与工程办公室的支持。
