平方公里阵列（SKA）将回答有关整个宇宙磁场的起源、演化、特性和影响的基本问题。磁场可以阐明和影响各种现象，如恒星形成、星系动力学、快速射电爆发、活动星系核、大尺度结构和暗物质湮灭。 SKA 的准备工作正在世界范围内迅速进行，并且该团体正在利用来自强大的国际 SKA 探路者和先驱望远镜套件的数据在宇宙磁学领域取得巨大的观测进展。在这篇文章中，我们根据最近的快速发展重新审视了使用 SKA 进行磁性研究的社区计划。我们特别关注新型射电望远镜仪器所产生的影响，从而增进我们对 SKA 磁科学关键领域以及处理和解释数据所需的新技术的理解。我们在 SKA 时代的最终科学目标的背景下讨论这些最新进展。
The Square Kilometre Array (SKA) will answer fundamental questions about the origin, evolution, properties, and influence of magnetic fields throughout the Universe. Magnetic fields can illuminate and influence phenomena as diverse as star formation, galactic dynamics, fast radio bursts, active galactic nuclei, large-scale structure, and dark matter annihilation. Preparations for the SKA are swiftly continuing worldwide, and the community is making tremendous observational progress in the field of cosmic magnetism using data from a powerful international suite of SKA pathfinder and precursor telescopes. In this contribution, we revisit community plans for magnetism research using the SKA, in light of these recent rapid developments. We focus in particular on the impact that new radio telescope instrumentation is generating, thus advancing our understanding of key SKA magnetism science areas, as well as the new techniques that are required for processing and interpreting the data. We discuss these recent developments in the context of the ultimate scientific goals for the SKA era.
