Jet propulsion of wind ejecta from a major flare in the black hole
  microquasar SS433
  We present direct evidence, from Adaptive-Optics near-infra-red imaging, of
the jets in the Galactic microquasar SS433 interacting with enhanced
wind-outflow off the accretion disc 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 disc 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 ten months prior to the observations. During this flare, excess
matter was expelled by the accretion disc 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 across the
W50 nebula by ROSAT.
