Recently, black hole X-ray binaries, consisting of a black hole several times the mass of the Sun and a companion star, have emerged as potential sources of cosmic rays. Some X-ray binaries eject fast-moving gas jets, which are believed to act as natural particle accelerators to create high-energy particles that streak across the Galaxy as cosmic rays.
V4641 Sgr is one such system, distinguished by its exceptional particle acceleration capabilities.
