Precision modeling for the Sunyaev-Zel'dovich Surveys

该项目的目的是对由Sunyaev-Zeldovich(SZ)效应引起的宇宙微波背景功率谱中的次级各向异性进行详细的模拟。这项工作将涉及分析和数值技术，以详细研究如何使用热SZ功率谱形状中包含的信息来揭示星系团内的介质，特别是在高红移和低质量的星系团中。该项目的结果将被纳入一个仿真工具，该工具将有助于从SZ功率谱的观测中估计宇宙学参数。该工具将向公众开放。这项工作的更广泛影响包括对本科生和研究生的培训，以及对博物馆和天文馆的推广。模拟的产品将被公开用于研究和课堂环境。

The aim of this project is to perform detailed modeling of the secondary anisotropies in the Cosmic Microwave Background power spectrum caused by the Sunyaev-Zeldovich (SZ) effect. The work will involve both analytic and numerical techniques to investigate in detail how the information contained in the shape of the thermal SZ power spectrum can be used to shed light on the intra-cluster medium, especially in clusters of galaxies at high redshifts and of low masses. The results of this project will be incorporated into an emulation tool that will aid cosmological parameter estimation from observations of the SZ power spectrum. This tool will be made publicly available. Broader impacts of the work include training of undergraduate and graduate students, and outreach to museums and planetariums. Products of the simulations will be made public for use in research and classroom settings.
