Discovery of minute-scale polarization angle rotation in a supermassive black hole jet
Aristeidis Polychronakis, Ioannis Liodakis, Dmitry Blinov +7
Relativistic jets from supermassive black holes oriented towards our line of sight called blazars have puzzled the astronomical community for decades. Their fast jets and preferent…
Tracking down the broadband polarimetric properties of PG 1553+113
Riccardo Middei, Svetlana G. Jorstad, Alan P. Marscher +78
We report on a nine-month monitoring campaign of the blazar PG 1553+113, relying on three observations carried out in 2025 with the Imaging X-ray Polarimetry Explorer (IXPE) and su…
The RoboPol Program: Optical Polarimetric Monitoring of Blazars
Dmitry Blinov, Vasiliki Pavlidou
After three years of polarimetric monitoring of blazars, the RoboPol project has uncovered several key characteristics of polarimetric rotations in the optical for these most varia…
Optical polarization variations in the blazar PKS 1749+096
Makoto Uemura, Ryosuke Itoh, Ioannis Liodakis +6
We report on the variation in the optical polarization of the blazar PKS 1749+096 observed in 2008--2015. The degree of polarization (PD) tends to increase in short flares having a…
Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
Polarization angle swings in blazars: The case of 3C 279
S. Kiehlmann, T. Savolainen, S. G. Jorstad +61
Over the past few years, several occasions of large, continuous rotations of the electric vector position angle (EVPA) of linearly polarized optical emission from blazars have been…
