Neutron Stars and Gravitational Waves from LIGO to Cosmic Explorer

该奖项支持相对论和相对论天体物理学的研究，它解决了NSF“宇宙之窗”大构想的优先领域。NSF LIGO探测到双中子星合并产生的引力波与从伽马射线到射电的电磁信号相吻合，为中子星内部打开了一扇窗。这些恒星包含了自宇宙大爆炸以来最极端条件下的物质。与脉冲星和超新星残余物相关的长时间连续引力波，以及与高磁化中子星的伽马射线耀斑相关的短爆发，一旦被探测到，将提供更多关于中子星内部的信息。计划中的宇宙探索者探测器将通过探测许多中子星合并和可能的各种其他信号来推动前沿。该奖项的科学目标是对这些新信号进行前沿搜索，并从现在和未来的信号中改进天体物理信息的提取。该奖项支持在西班牙裔服务机构培训研究生和本科生。学生将不仅在引力物理、数据分析和天体物理学方面接受培训，而且还将学习可转移到许多科学和技术领域的尖端计算和统计技术。该奖项还支持通过宇宙探索者网站进行公众宣传。该奖项的主要研究活动是寻找来自年轻中子星的连续引力波，包括已知脉冲星的r模振荡，以及超新星遗迹和其他非脉冲中子星的可能位置的搜索。该奖项还有助于搜索各种信号，包括中子星双星合并和与磁星耀斑相关的爆发，以及从现在和未来的探测中提取天体物理信息。为了准备探测非合并信号，该奖项支持探索可探测性以及现在和宇宙探索者时代可以了解的中子星。该奖项反映了美国国家科学基金会的法定使命，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。

This award supports research in relativity and relativistic astrophysics, and it addresses the priority areas of NSF's "Windows on the Universe" Big Idea. NSF LIGO’s detection of gravitational waves from a binary neutron star merger in coincidence with electromagnetic signals from gamma-rays to radio opened a window into the interiors of neutron stars. These stars contain matter under the most extreme conditions since the Big Bang. Long-lived continuous gravitational waves associated with pulsars and supernova remnants and short bursts associated with gamma-ray flares of highly magnetized neutron stars, once detected, will yield even more information on neutron star interiors. The planned Cosmic Explorer detector will push the frontiers forward by enabling detection of many neutron star mergers and probably a variety of other signals. The science goals of this award are to conduct cutting edge searches for these novel signals and improve the extraction of astrophysical information from present and future signals. This award supports the training of graduate and undergraduate students at a Hispanic Serving Institution. Students will be trained not only in gravitational physics, data analysis, and astrophysics, but in cutting edge computational and statistical techniques that are transferable to many areas of science and technology. This award also supports public outreach through the Cosmic Explorer web site.The main research activity of this award is searches for continuous gravitational waves from young neutron stars, including r-mode oscillations of known pulsars as well as searches of supernova remnants and other likely locations of non-pulsing neutron stars. This award also contributes to searches for a variety of signals including neutron star binary mergers and bursts associated with magnetar flares and to the extraction of astrophysical information from detections present and future. In preparation for the detection of non-merger signals the award supports exploration of detectability and what can be learned about neutron stars now and in the era of Cosmic Explorer.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.
