Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1
Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17
Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…

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…

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.…
