类轴子粒子与活动星系核的圆偏振

Axion-like particles and circular polarisation of active galactic nuclei

A. Payez, J. R. Cudell, D. Hutsemékers

摘要:

对类星体的可见光的线偏振的测量,有力地证明了它们的偏振矢量在天空的某些区域具有大尺度相干取向。我们表明,这些意见可以解释的混合非常轻的赝标量(类轴子)粒子在河外磁场在其传播过程中的光子。我们提出了一种新的处理波包和讨论的圆偏振。

英文摘要:

The measurements of the linear polarisation of visible light from quasars give strong evidence for large-scale coherent orientations of their polarisation vectors in some regions of the sky. We show that these observations can be explained by the mixing of the photons with very light pseudoscalar (axion-like) particles in extragalactic magnetic fields during their propagation. We present a new treatment in terms of wave packets and discuss the circular polarisation.
