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 polarization of accreting black holes: Cyg X-1 and Swift J1727.8-1613

M. Brigitte, J. Svoboda

The Imaging X-ray Polarimetry Explorer is an X-ray observatory measuring the X-ray polarization in the 2-8 keV energy range. Highly sensitive to the system's geometry, X-ray polari…

Disentangling the stellar atmosphere and the focused wind in different accretion states of Cygnus X-1

M. Brigitte, P. Hadrava, B. Kubátová +8

In high-mass X-ray binaries (HMXBs), the compact object accretes the strong stellar wind of an O-B supergiant companion star. X-ray flux variations alter the stellar wind's ionizat…
