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.

该奖项提供部分支持，使印度浦那大学间天文学和天体物理学中心（IUCAA）的科学家和学生能够与华盛顿州立大学（WSU）和加州理工学院（Caltech）的科学家和学生合作，为激光干涉仪引力波天文台（LIGO）进行数据分析。特别的重点将是开发工具和方法，以寻找可能由许多天文引力波源叠加而产生的引力波背景，这些引力波源太弱而无法单独检测。在访问美国期间，IUCAA的科学家（两名教师和一名研究生）将向美国同行介绍用于宇宙微波背景和射电天文学的相关探测方法。反过来，美国的学生和教师将培训IUCAA集团在信号模拟技术。这种信息交流将使每个小组能够在各自所在机构的项目中最大限度地发挥效力，同时继续通过互联网电话进行合作。在美国，IUCAA小组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。该奖项由物理学部和国际科学与工程办公室支持。
