Optical linear polarization measurements of quasars obtained with the Very Large Telescope at Paranal Observatory
D. Hutsemékers, B. Borguet, D. Sluse +1
We report 87 previously unpublished optical linear polarization measurements of 86 quasars obtained in May and October 2008, and from April to July 2015 with the Focal Reducer and…
Evidence for the alignment of quasar radio polarizations with large quasar group axes
Vincent Pelgrims, Damien Hutsemékers
Recently, evidence has been presented for the polarization vectors from quasars to preferentially align with the axes of the large quasar groups (LQG) to which they belong. This re…
Alignment of quasar polarizations with large-scale structures
Damien Hutsemékers, Lorraine Braibant, Vincent Pelgrims +1
We have measured the optical linear polarization of quasars belonging to Gpc-scale quasar groups at redshift z ~ 1.3. Out of 93 quasars observed, 19 are significantly polarized. We…
