J/A+A/441/915     Alignments of quasar polarization vectors (Hutsemekers+, 2005)

Mapping extreme-scale alignments of quasar polarization vectors Hutsemekers D., Cabanac R., Lamy H., Sluse D. <Astron. Astrophys. 441, 915 (2005)> =2005A&A...441..915H
ADC_Keywords: QSOs ; Polarization Keywords: quasars: general - polarization - large-scale structure of Universe - dark matter - cosmology: observations Abstract: Based on a new sample of 355 quasars with significant optical polarization and using complementary statistical methods, we confirm that quasar polarization vectors are not randomly oriented over the sky with a probability often in excess of 99.9%. Description: The table contains linear polarization measurements for 355 QSOs. File Summary:
