Description
We present direct evidence, from adaptive-optics near-infrared imaging, of the jets in the Galactic microquasar SS433 interacting with enhanced wind-outflow off the accretion disk that surrounds the black hole in this system. Radiant quantities of gas are transported significant distances away from the black hole approximately perpendicular to the accretion disk from which the wind emanates. We suggest that the material that comprised the resulting 'bow-tie' structure is associated with a major flare that the system exhibited 10 months prior to the observations. During this flare, excess matter was expelled by the accretion disk as an enhanced wind, which in turn is 'snow-ploughed', or propelled, out by the much faster jets that move at approximately a quarter of the speed of light. Successive instances of such bow-ties may be responsible for the large-scale X-ray cones observed within the W50 nebula by ROSAT.
