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.

该奖项支持相对论和相对论天体物理学的研究，并介绍了NSF“宇宙上的Windows”的优先领域。 NSF Ligo从二进制中子星合并从伽马射线到无线电的电磁信号从二进制中子星合并的重力波发现的引力波打开了一个窗户，进入了中子星的内部。这些恒星在大爆炸以来最极端的条件下包含物质。与脉冲星和超新星残留物相关的长期持续的重力波和与高度磁化中子星的伽马射线相关的短爆发，一旦被发现，就会产生有关中子星际内部的更多信息。计划中的宇宙探险仪检测器将通过探测许多中子星星并可能其他各种信号来推动边界向前。该奖项的科学目标是对这些新型信号进行最先进的搜索，并改善从现在和将来的信号中提取天体物理信息。该奖项支持西班牙裔服务机构的研究生和本科生的培训。学生将不仅接受引力物理学，数据分析和天体物理学的培训，而且还将接受转移到许多科学技术领域的尖端计算和统计技术中。该奖项还通过宇宙探险家网站支持公众宣传。该奖项的主要研究活动是搜索来自年轻的中子恒星的连续重力波，包括已知脉冲星的R模式振荡以及对超新星残留物的搜索以及其他可能的非垂体中子恒星的位置。该奖项还有助于搜索各种信号，包括中子星二进制合并和与磁片耀斑相关的爆发以及从目前和未来的探测中提取天体物理信息。在准备检测非合并信号的过程中，该奖项支持探索可检测性，以及现在和宇宙探险家时代可以学到的有关中性恒星的知识。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响审查标准来通过评估而被认为是珍贵的支持。
