ADVANCE Fellows Award: Cosmology with Sunyaev-Zeldovich Clusters

高级研究员奖：Sunyaev-Zeldovich星系团的宇宙学0340648 Pierpaolid.加州理工学院的Elena Pierpaoli将开展一个项目，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最大质量、最受引力约束的天体，几十年来，人们一直在研究它们，目的是约束宇宙学和了解结构形成。在过去，这些研究主要依靠光学和X射线信息。在不久的将来，预计将有更广泛和更深入的光学调查、高分辨率X射线图像、透镜研究以及通过SZ效应出现星团的射电(和近红外)地图的分析得出新的结果。这项研究将在几个领域产生广泛影响，包括为星团探测优化的代码，以及公开发布普朗克发射前星表。这项研究的副产品将是从模拟中产生SZ观测地图。这些将被用来完成已经为公众宣传而开发的集群形成的电影。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使科学家参与应用数学，使其成为跨学科的，并有可能在其他科学领域应用。合作的国际性将为参与其中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。

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.
