The Big Bang explosion at the beginning of the Universe left behind a glow of radiation in microwaves. Scientists using the next generation of microwave telescopes will study this radiation for signatures of primordial gravitational waves that are theorized but as yet unseen. These waves were created by quantum fluctuations during the Universe's first moments, and finding them would push the frontiers of physics. This project will develop mathematical, statistical, and computational tools to better map and analyze the data from these telescope measurements. It helps sponsor the research and training of the next generation of scientists at the undergraduate, graduate, and post-doctoral level. To ensure that exciting developments in early Universe research reach the broader community, this project focuses on attracting new students to STEM disciplines with public talks and school visits, college-level curriculum development, and high-quality STEM student mentoring.This project will advance the state of the art for Cosmic Microwave Background (CMB) analysis tools, with a focus on understanding and developing the role of the new "messenger method" approach to map-making and filtering. It will develop messenger map-making into a production-ready tool and apply it to data. Ground-based CMB observatories produce maps with complex, anisotropic noise correlations. Messenger methods can account for wider varieties of such correlations and serve as the basis for new power spectrum estimation tools. Additionally, messenger methods may allow for multiple tracers of the large-scale matter field to be combined with CMB lensing into a single tomographic matter atlas. The well-characterized synthesis of a mass map from multiple tracers is important for the epoch of wide field cosmology surveys. This project will promote the existing "Saturday Morning Physics" outreach lecture series at Florida State University and other K-12 activities. Furthermore, training of students, including undergraduates, helps to prepare the next generation of STEM workers.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.

宇宙诞生之初的大爆炸在微波中留下了辐射辉光。 科学家们将使用下一代微波望远镜来研究这种辐射，以寻找已理论化但尚未被发现的原始引力波的特征。 这些波是由宇宙诞生之初的量子涨落产生的，找到它们将推动物理学的前沿。 该项目将开发数学、统计和计算工具，以更好地绘制和分析这些望远镜测量数据。 它帮助资助下一代本科生、研究生和博士后科学家的研究和培训。 为了确保早期宇宙研究的令人兴奋的发展能够惠及更广泛的社区，该项目的重点是通过公开演讲和学校参观、大学水平课程开发和高质量的 STEM 学生指导来吸引新生进入 STEM 学科。该项目将推进宇宙微波背景 (CMB) 分析工具的最先进水平，重点是理解和发展新的“信使方法”方法在地图制作和过滤方面的作用。 它将把 Messenger 地图制作开发成一个可立即投入生产的工具，并将其应用于数据。 地面宇宙微波背景观测站生成具有复杂、各向异性噪声相关性的地图。 信使方法可以解释更广泛的此类相关性，并作为新功率谱估计工具的基础。 此外，信使方法可以允许将大规模物质场的多个示踪剂与 CMB 透镜结合成单个断层摄影物质图集。 来自多个示踪剂的质量图的良好表征对于广域宇宙学调查时代非常重要。 该项目将推广佛罗里达州立大学现有的“周六上午物理”系列外展讲座以及其他 K-12 活动。 此外，对学生（包括本科生）的培训有助于培养下一代 STEM 工作者。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
