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…

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…

A three-step approach to reliably estimate magnetic field strengths in star-forming regions
Aristeidis Polychronakis, Aris Tritsis, Raphael Skalidis +1
The magnetic field is known to play a crucial role in star formation. Dust polarization is an effective tool for probing the morphology of the field, yet it does not directly trace…
