Optical polarimetry of the accreting black hole X-ray binary Swift J1727.81613 over the state transition and radio ejections

Anagha P. Nitindala, Alexandra Veledina, Vadim Kravtsov +7

We present the first optical () polarimetric observations of Swift J1727.81613 during its 2023--2024 outburst. Observations were performed during the X-ray hard-to-soft sta…

Unveiling blazar synchrotron emission: a multiwavelength polarimetric study of HSP and LSP populations

Sara Capecchiacci, Ioannis Liodakis, Riccardo Middei +96

Polarimetric properties of blazars allow us to put constraints on the acceleration mechanisms that fuel their powerful jets. By studying the multiwavelength polarimetric behaviour…

Variability of X-ray polarization of Cyg X-1

Vadim Kravtsov, Anastasiia Bocharova, Alexandra Veledina +31

We present the results of a three-year X-ray, optical, and radio polarimetric monitoring campaign of the prototypical black hole X-ray binary Cyg X-1, conducted from 2022 to 2024.…

X-ray and multiwavelength polarization of Mrk 501 from 2022 to 2023

Chien-Ting J. Chen, Ioannis Liodakis, Riccardo Middei +143

We present multiwavelength polarization measurements of the luminous blazar Mrk~501 over a 14-month period. The 2--8 keV X-ray polarization was measured with the Imaging X-ray Pola…
