Black hole spin measurements in LMC X-1 and Cyg X-1 are highly model-dependent
Andrzej A. Zdziarski, Srimanta Banerjee, Swadesh Chand +4
The black-hole spin parameter, , was measured to be close to its maximum value of 1 in many accreting X-ray binaries. In particular, was found in a number of…
No Need for an Extreme Jet Energy in the Black-Hole X-Ray Binary MAXI J1348--630
Andrzej A. Zdziarski, Marek Sikora, Michal Szanecki +1
We model interaction with the surrounding medium of the main discrete jet ejection in the accreting black-hole binary MAXI J1348--630. The kinetic energy in the ejection of that je…
Evidence for a black hole spin--orbit misalignment in the X-ray binary Cyg X-1
Andrzej A. Zdziarski, Alexandra Veledina, Michal Szanecki +3
Recently, the accretion geometry of the black-hole X-ray binary Cyg X-1 was probed with the X-ray polarization. The position angle of the X-ray emitting flow was found to be aligne…
