This project will support the development, testing, and subsequent implementation of a fast data analysis pipeline for searching gravitational-wave (GW) signals from compact binary coalescences (CBCs) in the data of Advanced LIGO (aLIGO) and other second-generation detectors. These detectors are expected to make the first direct observations of gravitational waves and herald the birth of GW astronomy by harnessing information on the distribution of the sources in the sky, distance, masses, and spins. These observations may also shed light on the nature of the host galaxies of CBCs. This project will also support work on aLIGO commissioning and instrumentation at the Hanford site, and the development of rapid detector characterization techniques and tools. To catch a prompt electromagnetic or neutrino emission from a CBC it is critical that the duty factors of the GW detectors be high for sky localization, and detector characterization and background estimation be rapid so that robust GW alerts can be communicated to electromagnetic and neutrino observatories.Rapid detector characterization will facilitate the publishing of gravitational-wave data to the public, with robust data quality flags in hand. This project will also engage the faculty of the Washington State University campuses in Pullman and Tri-Cities in education and outreach on gravitational-wave science. The latter campus caters to a large percentage of Hispanic and Native-American populations, both of which are under-represented, and offers a rare setting for integrating university education with cutting-edge research in gravitation being carried out at a nearby lab.

该项目将支持从高级LIGO（ALIGO）和其他第二代探测器的数据中，从紧凑型二元合并（CBC）的搜索引力波（GW）信号进行快速数据分析管道的开发，测试和后续实施。预计这些探测器将通过利用有关在天空，距离，群体和旋转中分布的信息来对引力波的首次直接观察，并预示GW天文学的诞生。这些观察结果也可能阐明CBC的宿主星系的性质。该项目还将支持Hanford网站上Aligo调试和仪器的工作，以及快速探测器表征技术和工具的开发。 为了从CBC捕获迅速的电磁或中微子排放，至关重要的是，GW检测器的职责因素对于天空定位较高，并且探测器的表征和背景估计很快，因此可以将强大的GW警报传达给电磁和中微子的中微子和中微子守流器。该项目还将吸引华盛顿州立大学校园的铂尔曼和三城市的教育，并在重力波科学方面进行教育和宣传。后一个校园迎合了很大一部分西班牙裔和美国本地人的人口，这两者的代表性不足，并且为将大学教育与在附近的实验室进行的重力研究提供了罕见的环境。
