Workshop: DAWN2 - What's Next for LIGO?

随着2016年2月11日LIGO宣布探测到GW150914，引力波天文学的时代现在已经跨过了一个历史门槛。LIGO的第一次引力波事件为天体物理探索和数据分析开辟了新的途径，增强了直接探测的信息。应该记住，使LIGO成功的探测器是在近25年前首次构想出来的。因此，同样重要的是，现在是时候开始计划如何（以及在哪里）建造更灵敏的第三代探测器来探测宇宙中更高红移的引力波了。该奖项支持一个名为“DAWN2: LIGO的下一步是什么？”的研讨会，该研讨会将通过探索未来几年推进该领域的前景，并确定设计和实施下一代探测器所需的基础，来解决这一需求。本次论坛将介绍LIGO、LIGO科学合作组织和天体物理学合作伙伴从首次探测中获得的见解。与会者将讨论这些最初的几次检测如何为哪些途径提供最佳的前进机会提供信息，以及社区应如何开始为第二代和第三代仪器的国际网络制定计划。该研讨会将于2016年7月7日至8日在乔治亚理工学院举行。研讨会将分为三个部分，分别针对以下主题：近期和长期未来的先进LIGO，国际探测器网络和多信使天文学，国际社会对第三代探测器的长期规划。研讨会将举行三次会议，分别针对上面列出的每个主题，每次会议由科学组织委员会的一名成员主持。每个主题都将由不同观点的“愿景”演讲来介绍，然后休息和一个小时的讨论时间，通常是自由形式的，但由一个由该会议的演讲者加上一两个其他人组成的小组来主持。会议结束后，小组成员将捕获由演讲者和随后的讨论提出的想法和一致意见，并将其记录在一个或多个白皮书中。通过这种方式，人们希望能够形成一个更清晰的愿景，以提高LIGO探测器的科学潜力。这将有助于社区利用现有资源和新资源集中于关键技术发展和倡议。

With the 11 February 2016 announcement by LIGO of the detection of GW150914, the era of gravitational wave astronomy has now passed a historical threshold. LIGO's first gravitational wave event opens new avenues for astrophysical exploration and data analysis enhancements informed by direct detection. It should be recalled that the detectors that brought LIGO to success were first conceived almost a quarter century ago. Thus equally importantly, now is the time to start to plan how (and where) to build more sensitive third-generation detectors to probe the gravitational wave Universe to higher redshift. This award supports a workshop entitled "DAWN2: What's Next for LIGO?" which will address this need by exploring the prospects for advancing the field over the next several years and identifying the necessary groundwork for designing and implementing the next generation of detectors. This forum will be informed by insights gained by LIGO, the LIGO Scientific Collaboration and astrophysical partners from the first detections. Participants will discuss how these first few detections might inform which paths offer the best opportunities forward, and how the community should begin to develop plans for the international network of second and third generation instruments.The workshop will be held at the Georgia Institute of Technology on July 7-8, 2016. The workshop will have three sessions, one for each of the following topics: Advanced LIGO in the near and long term future, the international detector network and Multi-messenger astronomy, long term planning by the international community for 3rd generation detectors. The workshop will have three sessions, one for each of the topics listed above, each chaired by one of the members of the scientific organizing committee. Each topic will be introduced by "vision" talks from different points of view, which will be followed by a break and an hour of discussion time, generally freeform but moderated by a panel consisting of that session's speakers plus one or two others. After the meeting, the panelists will capture the ideas and consensus views that are brought forth by the presenters and the following discussion, and record them in one or more white papers. In this way, it is hoped that a clearer vision will take shape for ways to improve the scientific potential of the LIGO detectors. This should help the community focus on key technical developments and initiatives with existing and new resources.
