Nature Astronomy, Published online: 16 April 2026; doi:10.1038/s41550-026-02828-3 An 18-year high-resolution radio image dataset of Cygnus X-1 has revealed that its radio jets are bent by the stellar wind. Modelling of jet–wind interactions strongly supports the standard assumptions of an accreting black hole in cosmological simulations.
