项目摘要

At the vanguard of instrumental advances, gravitational wave (GW) detections shall drive profound discoveries at nature's extremes, with the potential of radically transforming the very concept of how we think of space, time, and gravity, as they open new doors to study previously hidden cosmic phenomena. The research program of the Columbia Experimental Gravity group (GECo) aims to maximize the science reach of upcoming gravitational wave discoveries and expand multimessenger science with gravitational waves. In particular, GECo will work on studying the cross correlation between LIGO GWs and neutrino detections from the IceCube observatory in the South Pole. Improved detectors are critical for seeing more of the cosmos with higher fidelity while astrophysically informed data analysis enable insight beyond the state of the art of Today. The aLIGO detectors were built to provide insight on elusive cosmic objects from black-holes to neutron-stars. Therefore GECo's program aims to improve the odds of discovering neutron-star containing binary systems and enhance the value of each discovery via enhanced detector and data analysis performance. In particular, GECo will work on the characterization of the LIGO detector as well as improving and maintaining the timing systems and developing new data analysis algorithms.Direct detections of gravitational waves provide an unprecedented opportunity born of new data to expose cosmic puzzles using multiple astrophysical messengers. At the root of new discoveries, there will be a multifaceted interplay between improved instruments, advanced understanding of the data, and innovative data analysis approaches relying on a comprehensive mesh of cosmic messengers. GECo will focus on the astrophysical, observational and experimental foundations of synergetic multimessenger campaigns, the firm base of new discoveries. GECo will utilize astrophysical as well as data structure priors to enhance the fidelity of the detections and to enable the confident detection of cosmic signals yet undetected. GECo aims to investigate multimessenger information, with special attention to neutrino counterparts and to enhance electromagnetic follow-up capabilities with low-latency coincident neutrino information. Multimessenger approaches have the potential to enhance the number of detectable sources as more distant, and abundant, cosmic events can become accessible. GECo also aims to investigate gravitational wave searches incorporating astrophysical priors on the properties of binary systems that can potentially enhance search sensitivity. GECo aims to contribute to the proper operation of advanced LIGO, to characterize the performance of mission critical detector subsystems, and to prepare in-depth reports to support exceptional gravitational wave candidates.

在工具进步的先锋队，引力波（GW）的探测应在自然界的极端发现深刻发现，并有可能从根本上改变我们对空间，时间和重力的看法，因为它们打开了新的门来研究以前隐藏的宇宙现象。哥伦比亚实验重力组（GECO）的研究计划旨在最大程度地提高即将到来的引力波发现的科学覆盖范围，并通过引力波扩大多中电学科学。特别是，GECO将研究从南极的Icecube天文台中的Ligo GWS与中微子检测之间的跨相关性。改进的探测器对于看到更多具有更高忠诚度的宇宙至关重要，而天体物理知情的数据分析使您能够超越当今艺术状态。 Aligo探测器的建造旨在提供对从黑洞到中子明星的难以捉摸的宇宙物体的见解。因此，GECO的计划旨在提高发现包含二进制系统的中子星的几率，并通过增强的检测器和数据分析性能增强每个发现的价值。特别是，GECO将致力于表征LIGO探测器，并改善和维持正时系统并开发新的数据分析算法。引力波的直接检测提供了一种前所未有的机会，可以使用多个天体物理学使者使用新数据来揭露宇宙困难。在新发现的根源下，改进的仪器，对数据的高级了解与依赖宇宙使者全面网格的创新数据分析方法之间将有一个多方面的相互作用。 GECO将重点关注新发现的牢固基础的Synergetic Multimessenger运动的天体物理，观察性和实验基础。 GECO将利用天体物理和数据结构先验来增强检测的保真度，并能够自信地检测宇宙信号，但未被发现。 GECO旨在调查多中微子的多中微子信息，并特别注意中微子的同类信息，并增强具有低延迟重合中微子信息的电磁随访功能。多通用器的方法有可能增加可检测到的来源的数量，因为可以访问更遥远和丰富的宇宙事件。 GECO还旨在研究在二元系统的性质上结合天体物理先验的引力波搜索，这些二元系统可能会增强搜索敏感性。 GECO旨在为高级LIGO的适当操作做出贡献，以表征任务关键探测器子系统的性能，并准备深入的报告以支持出色的引力候选者。
