  • NGC 7793−S26 is an extended source (350 pc × 185 pc) previously studied in the radio, optical and X-ray domains. It has been identified as a microquasar which has inflated a superbubble. We used integral-field spectra from the Wide-Field Spectrograph on the ANU 2.3-m telescope to analyse spectra between 3600 and 7000 A. This allowed us to derive fluxes and line ratios for selected nebular lines. Applying radiative shock model diagnostics, we estimate shock velocities, densities, radiative ages… CONTINUE READING
