Gravitational Waves From Compact Objects

本项目研究作为LIGO（Laser Interferometer Gravitational Wave Observatory）项目重要引力波源的中子星和/或黑洞的数据分析和建模。数据分析工作将包括开发、测试和使用算法和软件来对LIGO数据进行搜索。它还将包括从检测到的信号中提取信息的数学工作。二元动力学的建模是密切相关的：良好的数据分析需要对信号进行良好的预测。这个项目将集中于由旋转对象组成的二进制文件。对于这些系统，信号比通常考虑的要复杂得多。这使得搜索更加困难，但一旦检测到信号，可以提供更多的信息。鼓励学生研究数据分析问题以及源建模中涉及的传统重力和天体物理学。这为学生提供了比平常更广泛的培训，在学术界内外的职业生涯，解决实际和理论问题。学生将在科学会议上展示他们的工作。在此资助下开发的软件和数据分析技术将公开提供给国际LIGO科学合作组织使用。关于双星动力学的工作可能也会对天体物理学界产生影响。

This project studies data analysis and modeling of binary neutron stars and/or black holes, which will be an important source of gravitational waves for the LIGO project (Laser Interferometer Gravitational-wave Observatory). The data analysis work will include the development, testing, and use of algorithms and software to perform searches on LIGO data. It will also include mathematical work on extraction of information from detected signals. The modeling of binary dynamics is closely related: Good data analysis requires good predictions of the signals. This project will focus on binaries composed of spinning objects. For these systems the signals are much more complicated than those usually considered. This makes searches more difficult, but can provide much more information once a signal is detected.This project emphasizes graduate student participation. Students are encouraged to work on data analysis problems as well as the traditional gravity and astrophysics involved in source modeling. This provides students with broader than usual training for careers in and out of academia, solving practical as well as theoretical problems. Students will present their work at scientific meetings. Software and data analysis techniques developed under this grant will be publicly available and used by the international LIGO Science Collaboration. The work on binary dynamics may have implications of interest to the astrophysical community as well.
