In this project, techniques will be developed and tested to analyze data from advanced gravitational wave (GW) detectors including the Laser Interferometric Gravitational-Wave Observatory (LIGO) to search for GWs from astrophysical objects. There are two main targets of this project: rapidly rotating neutron stars (extremely dense objects more massive than the Sun and the size of a city, spinning tens to hundreds of times every second), and binary systems of black holes and/or neutron stars in the last seconds of the breakdown of their orbits due to GW emission.Gravitational waves (GWs), distortions of the geometry and space and time predicted by Einstein's General Theory of Relativity, provide a new window on the universe, allowing us to supplement the range of information available from different parts of the electromagnetic spectrum and from cosmic ray and neutrino observations. A modern generation of detectors including LIGO has been built and recently completed several years of observations which have resulted in limits on the strength and frequency of GW signals. These detectors are currently being upgraded to their advanced configuration, with an increased sensitivity which should provide the first direct GW detection in the near future. This project will involve faculty and students of the Rochester Institute of Technology in laying the groundwork for that first detection and the resulting groundbreaking expansion of our knowledge of the universe. In addition to the search for GWs, visualizations will be produced of gravitational-wave propagation and detection which will aid the general public's understanding of the science done by LIGO.

在该项目中，将开发和测试技术，以分析来自先进引力波探测器（GW）的数据，包括激光干涉引力波天文台（LIGO），以从天体物理物体中搜索引力波。 该项目有两个主要目标：快速旋转中子星（比太阳质量更大、城市大小的极致密物体，每秒旋转数十至数百次），以及黑洞和/或中子星的双星系统，在它们的轨道因GW发射而崩溃的最后几秒。引力波（GW）爱因斯坦的广义相对论所预言的几何和时空的扭曲，为我们提供了一个新的宇宙窗口，使我们能够补充从电磁波谱的不同部分以及从宇宙射线和中微子观测中获得的信息范围。 包括LIGO在内的现代一代探测器已经建成，最近完成了几年的观测，这导致了GW信号强度和频率的限制。 这些探测器目前正在升级到其先进的配置，具有更高的灵敏度，在不久的将来将首次提供直接的GW探测。 该项目将涉及罗切斯特理工学院的教师和学生，为第一次探测奠定基础，并由此开创性地扩大我们对宇宙的认识。 除了寻找GWs之外，还将产生引力波传播和探测的可视化，这将有助于公众对LIGO所做的科学的理解。
