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…

Polarisation angle variability in tidal disruption events

A. Floris, I. Liodakis, K. I. I. Koljonen +9

Tidal disruption events (TDEs) occur when a star is disrupted by the tidal forces of a supermassive black hole, and these events produce bright multi-wavelength flares. Polarimetri…

The IXPE and multifrequency polarimetric view of the extreme blazars 1ES 1101-232 and RGB J0710+591

Fabrizio Tavecchio, Dawoon E. Kim, Gabriel Emery +53

Multiwavelength polarimetry is a powerful tool to probe magnetic field and flow geometries in the relativistic jets of blazars. In this respect, particularly interesting are the so…

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…

Intra-night optical polarization monitoring of blazars

Aristeidis Polychronakis, Ioannis Liodakis, Anastasia Glykopoulou +20

Blazars are known for their extreme variability across the electromagnetic spectrum. Variability at very short timescales can push the boundaries between competing models offering…

Detection of Compton scattering in the jet of 3C 84

Ioannis Liodakis, Sudip Chakraborty, Frédéric Marin +77

3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low frequency radi…
