最近的观测结果表明,在红移[1-3]的星系和星系团中存在着$${\fancyscript{O}}(10^{-6})~\mathm{{G}}$$磁场。实现这一点的一个场景是银河发电机机制(例如[4])对磁场的放大,这需要在星系形成之前$${\fancyscript{O}}(10^{-20})~\mathm{{G}}$$种子场。
Recent observational consequences have shown the existence of $${\fancyscript{O}}(10^{-6}) ~\mathrm{{G}}$$ magnetic fields in galaxies and clusters of galaxies at redshift[1-3]. One of the scenarios to realize this is an amplification of the magnetic fields by the galactic dynamo mechanism (e.g. [4]), which requires $${\fancyscript{O}}(10^{-20}) ~ \mathrm{{G}}$$ seed fields prior to the galaxy formation.
