Probing the -ray emission region and the connection to jet ejections in NRAO 150 with VLBI

L. C. Debbrecht, G. F. Paraschos, E. Ros +7

Relativistic jets launched by active galactic nuclei are fundamental for understanding the physics of accreting supermassive black holes and their immediate environments, yet the o…

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…

A Ring of Fire Orphan γ-Ray Flare in the Neutrino Candidate 3C 120

E. Traianou, G. Bruni, J. Rodi +7

We present 43\,GHz VLBI observations of the radio galaxy 3C~120 during its brightest -ray outburst (March 2018), recently associated with the IceCube neutrino alert IC-180213A.…

Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry

Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97

RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…

Super-Eddington Accretion Geometry: a Remarkable Stability of the Hidden Ultraluminous X-Ray Source Cygnus X-3

Romana Mikušincová, Alexandra Veledina, Fabio Muleri +112

We report on the average and orbital phase-resolved polarization of Cyg X-3 in the hard state during the 2023 Imaging X-ray Polarimetry Explorer (IXPE) observational campaign. We f…

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…
