宇宙学中的大尺度磁场

Large-scale magnetic fields in cosmology

Christos G. Tsagas

摘要:

尽管磁场广泛存在,但其起源、演变和作用仍不清楚。原始磁性听起来很吸引人,但并非没有问题。磁场对宇宙大尺度结构的影响仍然是一个悬而未决的问题。本文概述了早期磁成因的优点和缺点,以及B场在线性构造形成情景中的典型作用。

英文摘要:

Despite the widespread presence of magnetic fields, their origin, evolution and role are still not well understood. Primordial magnetism sounds appealing but is not problem free. The magnetic implications for the large-scale structure of the universe still remain an open issue. This paper outlines the advantages and shortcomings of early-time magnetogenesis and the typical role of B-fields in linear structure-formation scenarios.
