Axions and polarisation of quasars
arXiv:0805.3946 · doi:10.1063/1.2987174
Abstract
We present results showing that, thanks to axion-photon mixing in external magnetic fields, it is actually possible to produce an effect similar to the one needed to explain the large-scale coherent orientations of quasar polarisation vectors in visible light that have been observed in some regions of the sky.
