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，并解决了NSF“宇宙之窗”大理念的优先领域。NSF LIGO探测到的来自双中子星星合并的引力波，与从伽马射线到无线电的电磁信号重合，打开了一扇了解中子星内部的窗户。这些恒星在大爆炸以来最极端的条件下含有物质。与超新星和超新星遗迹相关的长寿命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，将产生更多关于中子星星内部的信息。计划中的宇宙探测器将通过探测许多中子星星合并以及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尖端搜索，并改进从现在和未来信号中提取天体物理信息。该奖项支持在西班牙裔服务机构的研究生和本科生的培训。学生将接受培训，不仅在引力物理学，数据分析和天体物理学，但在尖端的计算和统计技术，可转移到科学和技术的许多领域。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搜索来自年轻中子星的连续引力波，包括已知中子星的r模式振荡，以及搜索超新星遗迹和其他可能的非脉冲中子星位置。 该奖项还有助于搜索各种信号，包括与磁星耀斑有关的中子星星双星合并和爆发，并有助于从目前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，该奖项支持对可探测性的探索，以及现在和宇宙探索者时代对中子星的了解。该奖项反映了NSF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.
