厘米和米波射电天文中的宇宙磁
Cosmic Magnetism in Centimeter and Meter Wavelength Radio Astronomy
摘要：
磁场在宇宙中无处不在，它在各种天体物理现象中起着至关重要的作用，但其真正的起源和演化却知之甚少。本文综述了当前对星际介质、银河系、外星系、活动星系核、星系团和宇宙网中磁场的认识。特别是，该评论集中在厘米和米波长的射电观测所提供的成就。本文还介绍了分析线偏振数据的各种方法，包括同步辐射、法拉第旋转、去偏振和法拉第层析成像。
英文摘要：
Magnetic field is ubiquitous in the Universe and it plays essential roles in various astrophysical phenomena, yet its real origin and evolution are poorly known. This article reviews current understanding of magnetic fields in the interstellar medium, the Milky Way Galaxy, external galaxies, active galactic nuclei, clusters of galaxies, and the cosmic web. Particularly, the review concentrates on the achievements that have been provided by centimeter and meter wavelength radio observations. The article also introduces various methods to analyze linear polarization data, including synchrotron radiation, Faraday rotation, depolarization, and Faraday tomography.
