The NSF's Advanced LIGO and the European Virgo observatory have established a new era in astronomy. The discoveries made by these second-generation gravitational-wave detectors have had a transformative impact, even though they are only able to observe a small fraction of the Universe. Taking full advantage of the rich promise of gravitational-wave astronomy will require a new network of third-generation detectors that can survey the Universe on its largest scales to provide answers to questions of broad interest in astrophysics, cosmology, fundamental physics, and nuclear physics. This award funds U.S. participation in the international effort to develop a third-generation gravitational-wave network; initiate a coordinated program to study third-generation gravitational-wave science targets, networks, and detector configurations; and support the U.S. role in planning the future of gravitational-wave astronomy. Third-generation detectors will expand humanity's ability to listen to the cosmic symphony of gravitational waves out to the very edge of the Universe. This award broadens opportunities for underrepresented students and provides students and postdocs with exposure to cutting-edge instrument technology, as well as project planning and management opportunities, positioning them well for scientific leadership positions. The technology development required to realize a next-generation detector will expand collaboration with and drive improvements in industry.This award leverages the decades-long investment by the NSF in LIGO and will position the U.S. to be a leadership partner in the future of gravitational-wave astronomy and physics. It will fund an effort to: (i) work with the Gravitational Wave International Committee (GWIC) to develop and document the international community's vision for third-generation science; (ii) extend the catalog of third-generation candidate detector designs, exploring configurations that were not included in previous international studies like the European Einstein Telescope; (iii) produce parametric cost estimates for the configurations that are identified; (iv) explore pathways to achieving a successful third-generation global network; and (v) define metrics for the network's discovery potential as a function of cost.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.

美国国家科学基金会的先进LIGO和欧洲室女座天文台开创了天文学的新纪元。 这些第二代引力波探测器的发现产生了变革性的影响，尽管它们只能观测到宇宙的一小部分。要充分利用引力波天文学的丰富前景，就需要一个新的第三代探测器网络，能够在最大尺度上观测宇宙，为天体物理学、宇宙学、基础物理学和核物理学中广泛关注的问题提供答案。该奖项资助美国参与开发第三代引力波网络的国际努力;发起一项协调计划，研究第三代引力波科学目标，网络和探测器配置;并支持美国在规划引力波天文学未来方面的作用。第三代探测器将扩大人类的能力，倾听宇宙的引力波交响乐，直到宇宙的边缘。该奖项拓宽了代表性不足的学生的机会，并为学生和博士后提供接触尖端仪器技术以及项目规划和管理的机会，使他们能够很好地担任科学领导职位。实现下一代探测器所需的技术开发将扩大与行业的合作并推动行业的改进。该奖项利用了美国国家科学基金会对LIGO长达数十年的投资，并将使美国成为未来引力波天文学和物理学的领导合作伙伴。它将资助以下努力：㈠与引力波国际委员会合作，制定和记录国际社会对第三代科学的看法; ㈡扩大第三代候选探测器设计的目录，探索以前的国际研究中没有包括的配置，如欧洲爱因斯坦望远镜; ㈢对确定的配置进行参数成本估计;（iv）探索实现成功的第三代全球网络的途径;（v）定义网络发现潜力的度量标准作为成本的函数。该奖项反映了NSF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。
