项目摘要

LIGO and its sibling collaborations continue to push forward the young field of gravitational wave astronomy. This grant focuses on Embry-Riddle's contributions to two facets of LIGO science. The first is detector characterization, which involves efforts to understand and mitigate the effects of Earth-based noise on the interferometer in order to detect gravitational waves with better clarity. The second is the search for gravitational waves from core-collapse supernovae, a promising source of gravitational wave emission beyond binary coalescences. Embry-Riddle is well positioned to advance the training of the next generation of scientists due to its focus on undergraduate education with close faculty-student interaction. Embry-Riddle's location, serving rural north-central Arizona, helps attract first-generation college students. Given its proximity to the Navajo nation, Embry-Riddle is also in a position to increase access to scientific opportunities for underrepresented minorities. The search for gravitational waves is made more difficult by the presence of terrestrial background, resulting from a combination of environmental disturbances and behavior of the interferometers themselves. Understanding these disturbances and removing them from interferometric data through detector characterization activities is critical in conducting sensitive searches for gravitational waves, as it can mean the difference between a statistically significant gravitational wave detection and a sub-threshold event. The PI of this proposal is a co-chair of LIGO's detector characterization working group, and will conduct a number of activities related to the continued operation of that group. Core-collapse supernovae (CCSNe) are an exciting target for multi-messenger astronomy. Given the rate of about two CCSNe per century in our galaxy, the signatures of the next Galactic CCSN are already traveling toward us. The reconstruction of a gravitational wave from a CCSN would address a number of open questions in astrophysics, including the mechanism of the explosion itself as well as fundamental questions about neutrino interactions and the neutron star equation of state. In the next few years, the improved sensitivity of Advanced LIGO combined with more sophisticated algorithms for detection and parameter estimation of supernova signals will greatly enhance LIGO's opportunities for exploring supernova astrophysics, and future interferometers carry even more promise.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.

LIGO及其兄弟合作继续推动年轻的引力波天文学领域。这项资助主要集中在Embry-Riddle对LIGO科学的两个方面的贡献。第一个是探测器特性鉴定，这涉及到努力了解和减轻地球噪声对干涉仪的影响，以便更清晰地探测引力波。第二个是寻找来自核心坍缩超新星的引力波，这是一个有希望的超越双星合并的引力波发射源。安柏瑞德是很好的定位，以推进下一代科学家的培训，由于其专注于本科教育与密切的师生互动。安柏里德尔的位置，服务于亚利桑那州中北部的农村，有助于吸引第一代大学生。由于靠近纳瓦霍民族，安柏里德尔还能够增加代表性不足的少数民族获得科学机会的机会。由于环境干扰和干涉仪本身的行为，地球背景的存在使得寻找引力波变得更加困难。了解这些干扰并通过探测器表征活动将其从干涉测量数据中消除，对于进行引力波的灵敏搜索至关重要，因为它可能意味着统计上显著的引力波探测和亚阈值事件之间的差异。该提案的PI是LIGO探测器表征工作组的联合主席，并将开展与该工作组持续运作相关的一些活动。核心坍缩超新星（CCSNe）是多信使天文学的一个令人兴奋的目标。考虑到我们银河系每世纪大约两个CCSN的速度，下一个银河系CCSN的签名已经向我们传播。从CCSN重建引力波将解决天体物理学中的许多悬而未决的问题，包括爆炸本身的机制以及关于中微子相互作用和中子星星状态方程的基本问题。在接下来的几年里，先进LIGO的灵敏度提高，结合更复杂的超新星信号检测和参数估计算法，将大大提高LIGO探索超新星天体物理学的机会，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进行评估，被认为值得支持的搜索.
