Gravitational waves are ripples in the curvature of spacetime that carry information about the changing gravitational fields of distant astrophysical objects. Gravitational waves will be a radically new tool for exploring the universe. This award supports the effort to detect gravitational waves from merging neutron stars and black holes with the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO). Black holes and neutron stars are nature's most compact objects and their collisions are a potentially transformative laboratory for fundamental physics and astrophysics. Gravitational-wave physics offers exciting opportunities to inspire and educate students of all ages, strengthening both the diversity and competitiveness of students and improving the scientific literacy of the general public. The proposed project will continue to drive the development of scientific workflow management tools and high-throughput computing that will have broad impact across the physics community.This award directly supports Advanced LIGO's effort to detect gravitational waves and to use gravitational waves as an astronomical tool to explore the Universe. This project focuses on coalescing compact binaries, with the effort dedicated towards developing, testing and using the LIGO Scientific Collaboration (LSC) deep, offline search pipeline for gravitational waves from compact binary coalescence. The primary goal of this project is to detect gravitational waves and to extract the astrophysics encoded in LIGO's signals. Engineering and science runs during the first two years of this proposal will allow the LSC to understand both the Advanced LIGO detectors and the search pipelines in an observational mode. Science runs during the second and third years of this proposal will produce astrophysical results. The first direct detection of gravitational waves could be made during the period of this award.

引力波是时空曲率中的涟漪，携带着遥远天体物理物体引力场变化的信息。引力波将成为探索宇宙的全新工具。该奖项支持利用先进激光干涉仪引力波天文台 (LIGO) 探测中子星和黑洞合并产生的引力波。黑洞和中子星是自然界最致密的天体，它们的碰撞是基础物理学和天体物理学潜在变革的实验室。引力波物理学为激励和教育各个年龄段的学生提供了令人兴奋的机会，增强了学生的多样性和竞争力，并提高了公众的科学素养。 拟议项目将继续推动科学工作流程管理工具和高通量计算的发展，这将对整个物理学界产生广泛影响。该奖项直接支持高级 LIGO 探测引力波以及利用引力波作为天文工具来探测引力波的努力。探索宇宙。该项目的重点是聚结致密双星，致力于开发、测试和使用 LIGO 科学合作组织 (LSC) 深度离线搜索管道来搜索致密双星聚结产生的引力波。该项目的主要目标是探测引力波并提取 LIGO 信号中编码的天体物理学信息。 该提案前两年的工程和科学运行将使 LSC 能够以观测模式了解高级 LIGO 探测器和搜索管道。该提案第二年和第三年的科学运行将产生天体物理学结果。首次对引力波的直接探测可能会在该奖项期间进行。
