Gravitational Wave Astrophysics With Advanced LIGO

引力波是时空曲率中的涟漪，它携带着遥远天体的引力场变化的信息。引力波将成为探索宇宙的全新工具。该奖项支持先进激光干涉仪引力波天文台（LIGO）探测合并中子星和黑洞产生的引力波的工作。黑洞和中子星是自然界最致密的物体，它们之间的碰撞是基础物理学和天体物理学潜在的变革实验室。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，加强了学生的多样性和竞争力，提高了公众的科学素养。拟议的项目将继续推动科学工作流管理工具和高通量计算的发展，这将对整个物理社区产生广泛的影响。这个奖项直接支持了高级LIGO探测引力波的努力，并将引力波作为一种天文工具来探索宇宙。该项目专注于合并紧密双星，致力于开发、测试和使用LIGO科学合作组织（LSC）的深度离线搜索管道，从紧密双星合并中寻找引力波。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。在这项提议的头两年里，工程和科学的运行将使LSC在观测模式下了解高级LIGO探测器和搜索管道。在这项提议的第二年和第三年进行的科学研究将得出天体物理学的结果。第一次对引力波的直接探测将在该奖项授予期间进行。

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.
