ADVANCE Fellows Awards: Cosmology with Sunyaev-Zeldovich ClustersABSTRACTAST 0340648 PierpaoliDr. Elena Pierpaoli, at the California Institute of Technology, will undertake a program to develop theoretical methods to extract physical and cosmological information from upcoming Sunyaev-Zeldovich (SZ) observations. Galaxy clusters are the most massive, gravitationally bound objects in our Universe, and their study has been pursued for several decades with the double aim of constraining cosmology and understanding structure formation. In the past these studies have mainly relied on optical and X-ray information. In the near future, new results are expected from wider and deeper optical surveys, high-resolution X-ray images, lensing studies and the analysis of the radio (and near-infrared) maps where clusters appear through the SZ effect.This research will produce broad impacts in several areas, including a code optimized for cluster detection, and the public release of the Planck pre-launch catalog. A by product of the research will be the production of SZ observed maps from the simulations. These will be used to complete movies of cluster formation already developed for public outreach. An addition of this research is the training of new scientists by involving them in modern research. Part of this activity will involve scientists in applied mathematics, rendering it interdisciplinary and potentially useful for application in other fields of science. The international character of the collaborations will provide an opportunity for the young scientists involved to travel aborad, further strengthening their professional development and integration into the international scientific community.

高级研究员奖：宇宙学与Sunyaev Zeldovich天文学家摘要0340648 PierpaoliDr。加州理工学院的埃琳娜·皮尔保利（Elena Pierpaoli）将开展一项计划，开发理论方法，从即将到来的Sunyaev-Zeldovich（SZ）观测中提取物理和宇宙学信息。 星系团是我们宇宙中质量最大的引力束缚物体，几十年来一直在进行研究，其双重目标是限制宇宙学和理解结构形成。 在过去，这些研究主要依赖于光学和X射线信息。 在不久的将来，通过更广泛和更深入的光学调查，高分辨率X射线图像，透镜研究和通过SZ效应出现的星团的无线电（和近红外）地图的分析，预计会有新的结果，这项研究将在几个领域产生广泛的影响，包括为星团探测优化的代码，以及公开发布普朗克发射前目录。 研究的一个副产品将是从模拟中产生SZ观测图。 这些将用于完成已经为公众宣传制作的集群形成影片。 这项研究的另一项内容是通过让新科学家参与现代研究来培训他们。 这项活动的一部分将涉及应用数学的科学家，使其成为跨学科的，并可能有助于在其他科学领域的应用。 合作的国际性质将为参与的青年科学家提供出国旅行的机会，进一步加强他们的专业发展和融入国际科学界。
