This project addresses the question of why galaxies look the way they do throughout the history of our universe. It will focus on the warm/hot gas that surrounds galaxies and provides them with fuel to form new stars. There is only incomplete theoretical understanding of the physical processes within galaxies that heat and alter this surrounding gas. This project will measure the imprint of this gas on leftover photons from the big bang which will provide new and critical information on the physics of these processes. This project will also run a pilot program to spark the interests of preschoolers in astronomy at two Agri-Business Child Development (ABCD) centers. The ABCD program offers comprehensive early childhood education to low-income families where both parents are agriculturally employed. This project will constrain feedback processes in galaxies using cross-correlation measurements from large-scale structure surveys and cosmic microwave background (CMB) experiments. Feedback processes play an important role in theories of galaxy formation and evolution. They are thought to regulate star formation in galaxies and affect the large-scale distribution of matter in our universe. An essential aspect of feedback not well understood is its impact on the reservoirs of warm/hot ionized gas that surrounds galaxies, the circumgalactic medium (CGM), which provides galaxies with new or recycled material to form new generations of stars. This project uses observations of additional fluctuations in the CMB (specifically the Sunyaev-Zeldovich effects) to probe the thermodynamic history of the CGM and provide essential information on the role of feedback in galaxy formation and evolution.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.

这个项目解决了为什么星系在我们宇宙的历史中看起来是这样的问题。 它将专注于围绕星系的温暖/炽热气体，并为它们提供燃料以形成新的恒星。对于星系内加热和改变周围气体的物理过程，只有不完整的理论理解。该项目将测量这种气体在大爆炸遗留光子上的印记，这将为这些过程的物理学提供新的关键信息。该项目还将在两个农业企业儿童发展（ABCD）中心开展试点项目，激发学龄前儿童对天文学的兴趣。ABCD计划为父母双方都从事农业的低收入家庭提供全面的幼儿教育。 该项目将利用大规模结构调查和宇宙微波背景实验的互相关测量来限制星系中的反馈过程。反馈过程在星系形成和演化理论中起着重要的作用。它们被认为调节着星系中星星的形成，并影响着我们宇宙中物质的大尺度分布。反馈的一个重要方面没有得到很好的理解，是它对星系周围温暖/热电离气体的储存库的影响，环星系介质（CGM），它为星系提供新的或回收的材料，以形成新一代的恒星。该项目利用对宇宙微波背景辐射额外波动的观察（特别是苏尼亚耶夫-泽尔多维奇效应）来探索CGM的热力学历史，并提供有关反馈在星系形成和演化中的作用的重要信息。该奖项反映了美国国家科学基金会的法定使命，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。
