[en] Photon - axion conversion within a magnetic field over cosmological distances can affect the polarization of distant objects like quasars. We report the observation of large-scale alignments of quasar polarization vectors as well as a rotation of their polarization angles with distance. This effect might be due to the presence of axions along the line of sight.
