A new analysis of quasar polarisation alignments
arXiv:1402.4313 · doi:10.1093/mnras/stu966
Abstract
We propose a new method to analyse the alignment of optical polarisation vectors from quasars. This method leads to a definition of intrinsic preferred axes and to a determination of the probability $p^Ï$ that the distribution of polarisation directions is random. This probability is found to be as low as 0.003% for one of the regions of redshift.
