中文简介:
宇宙微波背景(CMB)温度各向异性和偏振测量是建立当前宇宙学模型的关键宇宙学探针之一。欧空局的PLANCK任务旨在提供全天空覆盖、低噪声水平、高分辨率温度和偏振图。我们将简要回顾PLANCK数据分析的一些关键问题,并介绍如何使用稀疏性来分析此类数据集,特别是学习如何将CMB与其他天空分量分离。
课程简介: Cosmic Microwave Background (CMB) temperature anisotropies and polarisation measurements have been one of the key cosmological probes to establish the current cosmological model. The ESA’s PLANCK mission is designed to deliver full-sky coverage, low-noise level, high resolution temperature and polarisations maps. We will briefly review some of the key problem of the PLANCK data analysis, and we will present how sparsity can be used to analyze such data set, especially for learning how to separate the CMB from other sky components.
关 键 词: 宇宙微波背景; 高分辨率; 偏振测量
