Large-scale coherent orientations of quasar polarisation vectors: interpretation in terms of axion-like particles

  • 1. University of Liege, Allee du 6 Aout 17, 4000 Liege (Belgium)

Description

The observation of redshift-dependent coherent orientations of quasar polarisation vectors over cosmological distances in some regions of the sky is reviewed. Based on a good-quality sample of 355 measured quasars, this observation seems to infer the existence of a new effect acting on light propagation on such huge distances.A solution in terms of nearly massless axion-like particles has been proposed in the literature and its current status is discussed.
