Eve Vavagiakis is awarded an NSF Astronomy and Astrophysics Fellowship to carry out a program of research and education at Cornell and Princeton universities. Vavagiakis will undertake a program of data analysis and instrumentation development to advance the use of cosmic microwave background (CMB) anisotropies such as the Sunyaev-Zel'dovich (SZ) effect for cosmological measurements. Results from the project will allow astronomers to understand properties of galaxy clusters and shed light on galaxy evolution and cosmology. For the education component of this project, Vavagiakis will conduct astronomy outreach to local high schools, develop educational materials to accompany a children’s book series featuring modern NSF-funded experiments, and provide research mentoring for underserved and underrepresented students.This research project will enable the highest significance measurement of the pairwise kinetic SZ effect and advance future SZ measurements to constrain fundamental physics. To achieve this goal, Vavagiakis will: analyze CMB maps from the Atacama Cosmology Telescope combined with data from the Dark Energy Spectroscopic Instrument; deploy a cryogenic array camera based on kinetic inductance detectors (KIDs) that she designed for early science with a new submillimeter telescope; and develop an extended multifrequency pipeline for SZ analyses for existing and planned CMB telescopes. By demonstrating the background-limited sensitivity of KIDs, this project might help establish them as detectors of choice for future millimeter and submillimeter telescopes.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.

Eve Vavagiakis被授予NSF天文学和天体物理学奖学金，以在康奈尔大学和普林斯顿大学进行研究和教育计划。 Vavagiakis将采用数据分析和仪器开发计划，以推动宇宙微波背景（CMB）各向异性的使用，例如Sunyaev-Zel'Dovich（SZ）效应宇宙学测量。该项目的结果将使天文学家能够了解星系簇的特性，并阐明银河发展和宇宙学。对于该项目的教育组成部分，Vavagiakis将向当地高中进行天文学宣传，开发教育材料，以参与以现代NSF资助的实验为特色的儿童书籍系列，并为服务不足和代表性不足的学生提供心理研究。这项研究项目将对SZ SZ SZ效应的最高意义衡量，以促进SZ SZ效应的最高意义，以实现SZ SZ效应的最高意义。为了实现这一目标，Vavagiakis将：分析来自Atacama Cosmology望远镜的CMB图与深色能量光谱仪器的数据相结合；根据动力学电感探测器（KIDS）部署低温阵列相机，她为早期科学设计，并使用新的亚毫米望远镜设计；并为现有和计划的CMB望远镜进行SZ分析开发扩展的多频管道。通过证明孩子的背景限制敏感性，该项目可能有助于将他们确立为未来毫米和亚毫米望远镜的首选探测器。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响审查标准来评估来获得支持的。
