类星体极化中的对准:存在关联磁场时的赝标量光子混合

Alignments in quasar polarizations: pseudoscalar-photon mixing in the presence of correlated magnetic fields

Nishant Agarwal, Archana Kamal, Pankaj Jain

摘要:

我们研究了在关联河外磁场存在下赝标量光子混合对电磁辐射的影响。我们将宇宙模拟为磁畴的集合,并研究辐射通过它们的传播。这导致了斯托克斯参数之间的相关性在大尺度上,并始终解释了观察到的大尺度排列的类星体偏振在不同的红移范围内的大爆炸模型的框架。

英文摘要:

We investigate the effects of pseudoscalar-photon mixing on electromagnetic radiation in the presence of correlated extragalactic magnetic fields. We model the Universe as a collection of magnetic domains and study the propagation of radiation through them. This leads to correlations between Stokes parameters over large scales and consistently explains the observed large-scale alignment of quasar polarizations at different redshifts within the framework of the big bang model.
