Conceptual scheme of the MQ S26, not to scale. The stellar-mass BH and the Wolf-Rayet star are in the core. The extended lobes are at the ends of the two opposite jets, where shocks form at the hotspots. There, the backward shock accelerates particles to relativistic energies, producing synchrotron radio emission, and the forward radiative shock produces optically thin thermal X-ray emission. Nonthermal X-ray emission is produced by the electron-synchrotron mechanism at the base of the jet in the core, close to the BH but above the photosphere of the disk-driven wind.
