This award supports research in gravitational wave detector data analysis, and it addresses the priority areas of NSF's "Windows on the Universe" Big Idea. With the gravitational wave detection of the coalescence of a binary neutron star system by the Laser Interferometer Gravitational-wave Observatory (LIGO) on August 17, 2017, the near-simultaneous detection of gamma-ray emission from the same region of the sky by Fermi, and the highly successful followup of the electromagnetic counterpart from X-rays to radio waves, the era of multimessenger gravitational-wave astronomy began. The Advanced LIGO detectors are now in their third observing run. In coordination with the European Virgo detector and eventually the Japanese KAGRA detector, this network of gravitational wave observatories will survey the universe with unprecedented sensitivity. A trove of new discoveries is at hand. This grant supports the research activities of the University of Wisconsin--Milwaukee (UWM) LIGO Scientific Collaboration (LSC) group. The overarching theme is gravitational-wave astronomy with an emphasis on activities that are on the critical path for the scientific success of LIGO and its full participation in multimessenger transient astronomy. This project brings highly-engaged faculty with a proven track record in gravitational physics, astrophysics, data analysis, education and outreach together with undergraduates, graduate students and postdocs in a close collaborative environment to deliver science at the dawn of multimessenger gravitational-wave astronomy. This project supports the creation of critical components of a system that will allow the rapid transmittal of gravitational-wave observations to the entire community of astronomers via open public alerts, and facilitates the integration of gravitational-wave science into the broader field of astrophysics. The excitement of this budding branch of astronomy is brought to the community through outreach efforts such as the UWM Planetarium.The UWM LSC group will deliver several critical elements to a low-latency, streaming search for transient gravitational waves, including those produced during the coalescence of binary neutron stars and/or black holes. Among the data analysis elements that will be developed and operated are the online search for signals from compact binary coalescence, a near real-time source classification system, and a rapid parameter estimation utility. A system to rapidly identify signals will be an essential element of gravitational-wave science in the era of multimessenger astronomy in which observations of several kinds (gravitational waves; electromagnetic waves; high energy particles) are synthesized to obtain a detailed understanding of the sources of the most cataclysmic events in the universe. Gravitational-wave astronomy will reveal the inner mechanism of gamma-ray bursts, will provide a means to measure the population of black holes and determine the channel by which massive black holes are grown, and will probe the fundamental nature of matter above nuclear densities. New ways of measuring cosmological parameters will become available, which will complement existing observations. To this end, this project supports work, identified as critical path in the LSC Data Analysis White Paper and the LSC Program, that will result in gravitational-wave detections of binary coalescence, provide rapid sky localization and parameter estimation to facilitate electromagnetic follow-up efforts, yield fast turn-around targeted searches prompted by triggers generated by other observational facilities, obtain the nuclear equation of state by measuring the tidal interactions of binary neutron stars just prior to their merger, and exploit gravitational wave observations to measure various cosmological parameters.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持引力波探测器数据分析的研究，并解决了NSF“宇宙之窗”大构想的优先领域。2017年8月17日，激光干涉仪引力波天文台（Laser Interferometer gravitational-wave Observatory，简称LIGO）探测到双中子星系统合并的引力波，费米望远镜几乎同时探测到来自天空同一区域的伽马射线发射，以及从x射线到无线电波的电磁对应体的高度成功跟进，多信使引力波天文学的时代开始了。先进的LIGO探测器现在正在进行第三次观测。在欧洲处女座探测器和最终日本KAGRA探测器的配合下，这个引力波观测网将以前所未有的灵敏度探测宇宙。一大批新发现就在眼前。这笔拨款支持威斯康星大学密尔沃基分校（UWM） LIGO科学合作（LSC）小组的研究活动。总体主题是引力波天文学，重点是在LIGO科学成功的关键路径上的活动，以及它在多信使瞬态天文学中的充分参与。该项目汇集了在引力物理学、天体物理学、数据分析、教育和推广方面有着良好记录的高度敬业的教师，以及本科生、研究生和博士后，在一个密切合作的环境中，在多信使引力波天文学的黎明时分提供科学。该项目支持创建一个系统的关键组件，该系统将允许通过公开的公共警报向整个天文学家社区快速传输引力波观测数据，并促进引力波科学融入更广泛的天体物理学领域。这一新兴天文学分支的兴奋之情是通过威斯康星大学天文馆等外展努力带给社区的。UWM LSC小组将提供几个关键元素，用于低延迟、流搜索瞬态引力波，包括在双中子星和/或黑洞合并期间产生的引力波。将开发和操作的数据分析元素包括从紧凑二进制合并中在线搜索信号，近实时源分类系统和快速参数估计实用程序。在多信使天文学时代，一个快速识别信号的系统将是引力波科学的一个基本要素，在这个时代，多种观测（引力波、电磁波、高能粒子）被综合起来，以获得对宇宙中最灾难性事件来源的详细了解。引力波天文学将揭示伽马射线爆发的内部机制，将提供一种测量黑洞数量和确定大质量黑洞生长通道的方法，并将探索核密度以上物质的基本性质。测量宇宙学参数的新方法将成为可能，这将补充现有的观测。为此，该项目支持在LSC数据分析白皮书和LSC计划中确定为关键路径的工作，这些工作将导致引力波双并合探测，提供快速的天空定位和参数估计，以促进电磁后续工作，产生由其他观测设施产生的触发触发的快速转身目标搜索。通过测量双中子星合并前的潮汐相互作用获得核状态方程，并利用引力波观测测量各种宇宙学参数。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
