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…

Exploring MAXI J1744-294: IXPE insights into a Newly Discovered X-ray Transient

Lorenzo Marra, Romana Mikušincová, Federico M. Vincentelli +33

We present the first IXPE spectro-polarimetric observation of the black hole candidate MAXI J1744294, a transient X-ray source discovered during a bright 2025 outburst in the Ga…

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 optical polarization aligned with the radio jet ejecta in GX 339-4

G. Mastroserio, B. De Marco, M. C. Baglio +27

We present the first X-ray polarization measurements of GX 339-4. IXPE observed this source twice during its 2023-2024 outburst, once in the soft-intermediate state and again durin…
