Cosmic anisotropies from quasars: from polarization to structural-axis alignments
Vincent Pelgrims
The comparison of the orientations of the optical-polarization vectors of quasars that are separated by billions of light-years has led to the discovery that they are aligned inste…
A new test of uniformity for object orientations in astronomy
Vincent Pelgrims
We briefly present a new coordinate-invariant statistical test dedicated to the study of the orientations of transverse quantities of non-uniformly distributed sources on the celes…
Polarization alignments of radio quasars in JVAS/CLASS surveys
Vincent Pelgrims, Damien Hutsemékers
We test the hypothesis that the polarization vectors of flat-spectrum radio sources (FSRS) in the JVAS/CLASS 8.4-GHz surveys are randomly oriented on the sky. The sample with robus…
A new analysis of quasar polarisation alignments
Vincent Pelgrims, Jean-Rene Cudell
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…
