Next Generation Data Analysis For Next Generation Cosmic Microwave Background Experiments.

宇宙诞生之初的大爆炸留下了微波辐射。 使用下一代微波望远镜的科学家将研究这种辐射，以寻找理论上尚未发现的原始引力波的特征。 这些波是由宇宙最初时刻的量子波动产生的，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，以更好地映射和分析这些望远镜测量的数据。 它帮助赞助下一代科学家在本科生，研究生和博士后水平的研究和培训。 为了确保早期宇宙研究的令人兴奋的发展能够传播到更广泛的社区，该项目的重点是通过公开讲座和学校参观，大学水平的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）分析工具的最新发展，重点是理解和发展新的“信使方法”在地图制作和过滤方面的作用。 它将把信使地图制作发展成为一种生产就绪工具，并将其应用于数据。 地面CMB观测站产生的地图具有复杂的各向异性噪声相关性。 信使的方法可以解释更广泛的品种，这种相关性，并作为新的功率谱估计工具的基础。 此外，信使方法可以允许将大尺度物质场的多个示踪剂与CMB透镜结合成单个断层物质图谱。 从多个示踪剂合成质量图的良好表征对于宽场宇宙学调查时代是重要的。 这个项目将促进现有的“星期六上午物理”在佛罗里达州立大学和其他K-12活动的推广讲座系列。 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。

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.
