This award supports research in relativity and relativistic astrophysics and it addresses the priority areas of NSF's "Windows on the Universe" Big Idea. The era of gravitational-wave multi-messenger astronomy started on 2017 August 17, when LIGO (the Laser Interferometer Gravitational Wave Observatory) discovered an event dubbed GW170817. This was the very first direct observation of gravitational waves from a binary neutron star in-spiral, which was accompanied by the detection of light at all wavelengths. The multi-messenger observations of GW170817 have crucially informed a large variety of fields including gravitational physics, nuclear physics, cosmology, and relativistic astrophysics. In spite of the spectacular progress, several questions remain open. A key one is whether the stellar object leftover from the merger is a short-lived neutron star, a long-lived neutron star, or a promptly formed black hole. This award supports searches of LIGO data for signatures aimed at uncovering the nature of the merger remnant. Studying how the nature of the remnant depends on the properties of the merging objects can unlock the fundamental physics of matter at densities much larger than those that can be probed in Earth-based laboratories and clarify the physics of some of the most exotic objects in the stellar graveyard. This project also supports the training of graduate and undergraduate students who will constitute the next generation of scientists, and several outreach activities aimed at presenting LIGO results to the general public and K12 students. Specific intellectual goals are: (i) Unmasking the remnants of compact object mergers accompanied by gamma-ray bursts by carrying out searches for gravitational waves from newly formed neutron stars; (ii) Assessing the efficiency of the newly-developed Cross-Correlation Algorithm (CoCoA) in detecting the full zoo of possible gravitational wave signals from merger remnants, and its efficacy in post-detection parameter estimation; (iii) Quantifying the potential for discovery of gravitational waves from neutron stars formed in long gamma-ray bursts by future upgraded gravitational wave detectors. Broader impact goals are: (i) Bringing age-appropriate presentations and LIGO-related outreach activities to under-represented groups by leveraging the TTU Honors College-Bayless Elementary School mentoring program; (ii) Presenting a LIGO prize to the South Plains Regional Science Fair; (iii) Presenting LIGO results to the general public during the Astronight at TTU.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，并涉及美国国家科学基金会“宇宙之窗”大创意的优先领域。引力波多信使天文学的时代开始于2017年8月17日，当时LIGO（激光干涉仪引力波天文台）发现了一个被称为GW170817的事件。这是对螺旋双中子星引力波的首次直接观测，同时还检测到了所有波长的光。 GW170817 的多信使观测为包括引力物理学、核物理学、宇宙学和相对论天体物理学在内的众多领域提供了至关重要的信息。尽管取得了惊人的进展，但仍有几个问题悬而未决。关键在于合并留下的恒星物体是短命中子星、长命中子星还是迅速形成的黑洞。该奖项支持对 LIGO 数据进行签名搜索，旨在揭示合并残余物的性质。研究残余物的性质如何取决于合并物体的特性，可以解开密度远大于地球实验室可探测物质的基本物理原理，并阐明地球上一些最奇特物体的物理原理。恒星墓地。该项目还支持培养将成为下一代科学家的研究生和本科生，以及旨在向公众和 K12 学生展示 LIGO 结果的多项外展活动。具体的智力目标是：（i）通过搜索新形成的中子星的引力波，揭示伴随伽马射线爆发的致密天体合并的残余物； (ii) 评估新开发的互相关算法（CoCoA）在检测来自合并残余物的所有可能的引力波信号方面的效率，及其在检测后参数估计中的功效； (iii) 量化未来升级的引力波探测器发现长伽马射线爆发中形成的中子星引力波的潜力。更广泛的影响目标是： (i) 利用 TTU 荣誉学院-贝勒斯小学辅导计划，为代表性不足的群体提供适合年龄的演讲和 LIGO 相关的外展活动； (ii) 向南部平原地区科学博览会颁发 LIGO 奖； (iii) 在 TTU 的 Astronight 期间向公众展示 LIGO 结果。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
