This award supports the attendance of US scientists to the fourth workshop in the DAWN series, DAWN IV - Global Strategies for Gravitational Wave Astronomy - which will take place in Amsterdam, Netherlands, during August 30-31, 2018. The meeting is hosted by NIKHEF, affiliated to the Virgo project, with an international committee in charge of the scientific organization of the workshop. The main goal of the meeting is to discuss the science and R&D requirements for the next generation of ground-based gravitational wave (GW) detectors and the different options for the governance of a global detector network. Dozens of US scientists are now involved in a study commissioned by the Gravitational Wave International Committee (GWIC) to assess the scientific merit of building detectors on the ground that are 10 to 30 times more sensitive than advanced detectors. DAWN IV is a critical meeting for people involved in this study.LIGO and Virgo discoveries of binary black hole and binary neutron star mergers in the past three years have already begun to make a huge impact in our understanding of fundamental physics, astrophysics and cosmology. Merging binary black holes are test beds of strong field gravity; they are the only way to understand dynamical horizons around black holes. In contrast, observation of coalescing neutron stars has confirmed that they are the progenitors of short, hard, gamma-ray bursts and sites where heavy elements are formed. Simultaneous observation of GW170817 across the entire electromagnetic band and the GW window has ushered in a new era in multi-messenger astrophysics and cosmology, enabling the first ever measurement of the Hubble constant. This workshop will accomplish three main objectives: (i) identify the broader community of physicists and astrophysicists to facilitate infusion of new ideas in GW experiments, (ii) discuss steps that are necessary to increase participation of minority groups and hence enhance the diversity within the GW science, and (iii) determine strategies for interfacing with funding agencies and governments, and public engagements. The workshop will assure leadership of NSF-funded US scientists in the emerging area of GW astronomy.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.

该奖项支持美国科学家参加将于2018年8月30日至31日在荷兰阿姆斯特丹举行的黎明系列第四次研讨会--曙光IV--引力波天文学的全球战略。会议由隶属于处女座项目的nikhef主办，一个国际委员会负责研讨会的科学组织。会议的主要目标是讨论下一代地面引力波(GW)探测器的科学和研发要求，以及管理全球探测器网络的不同选择。数十名美国科学家目前参与了一项由引力波国际委员会(GWIC)委托进行的研究，以评估在地面上建造探测器的科学价值，这些探测器的灵敏度是先进探测器的10到30倍。黎明四号对于参与这项研究的人来说是一个关键的会议。LIGO和处女座在过去三年中发现的双星黑洞和双星中子星合并已经开始对我们对基础物理、天体物理和宇宙学的理解产生巨大的影响。合并双星黑洞是强场引力的试验台；它们是理解黑洞周围动力学视界的唯一途径。相比之下，对聚结中子星的观察证实，它们是短而硬的伽马射线爆发的先驱，也是重元素形成的场所。在整个电磁波段和GW窗口同时观测GW170817开创了多信使天体物理学和宇宙学的新纪元，使首次能够测量哈勃常数成为可能。该讲习班将实现三个主要目标：(I)确定更广泛的物理学家和天体物理学家社区，以促进在全球地球科学实验中注入新的思想；(Ii)讨论增加少数群体的参与从而增强全球地球科学内部多样性所必需的步骤；以及(Iii)确定与资助机构和政府以及公众参与的对接战略。研讨会将确保NSF资助的美国科学家在全球天文学新兴领域的领导地位。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
