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直接探测带来的数据分析增强开辟了新的途径。应该记得，使LIGO获得成功的探测器最初是在近25年前构思出来的。因此，同样重要的是，现在是时候开始计划如何(以及在哪里)建立更灵敏的第三代探测器，以探测更高红移的引力波宇宙。该奖项支持一个名为“DAWN2：LIGO的下一步是什么？”的研讨会。它将通过探索在未来几年推进这一领域的前景并确定设计和实施下一代探测器的必要基础来满足这一需要。本论坛将从LIGO、LIGO科学协作和天体物理合作伙伴从首次探测中获得的见解中获得信息。与会者将讨论这些最初的几个检测如何提供最好的前进机会，以及社区应该如何开始为第二代和第三代仪器的国际网络制定计划。研讨会将于2016年7月7-8日在佐治亚理工学院举行。讲习班将举行三次会议，每期一次，分别用于下列专题：近期和长期的高级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。研讨会将有三场会议，分别针对上述主题，每场会议由科学组织委员会的一名成员担任主席。每一议题都将由从不同角度进行的“愿景”演讲介绍，随后将有休息时间和一小时的讨论时间，讨论时间通常是自由的，但由该会议的发言者和其他一至两名发言者组成的小组主持。会议结束后，小组成员将收集演讲者提出的想法和共识观点以及随后的讨论，并将其记录在一份或多份白皮书中。通过这种方式，人们希望在如何提高LIGO探测器的科学潜力方面形成更清晰的愿景。这应有助于社区利用现有和新的资源，专注于关键的技术发展和倡议。

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.
