In both configurations, we see the distinct signature of the precessing jet on the bent jet emission patterns formed, as well as on resolution effects at a faster pace than the rest of runs.
The precessing jet sweeps across more of the ambient matter in a given period of time, as compared to an otherwise same but nonprecessing jet (run2-scenario), with both jet examples considered to be moving through identical surroundings.
The precessing jet model was therefore run, at an accelerated precession rate, and that showed an enhanced effect of sweeping the accretion disk wind matter from the jet cone.
It is, therefore, the accretion disk wind matter that is mainly expelled from the incoming jet and rushed outwards, swept over by the precessing jet. This finding might suggest a behaviour that over a much longer timescale leads to the formation of a "ruff" of material, around the cone swept by the precessing jet, perhaps along the lines of the "bow-tie" structure recently observed in SS433 .
This happens because the precessing jet covers a cone with an opening angle much larger than the jet's own.
The above discussed runs with the hydrocode PLUTO have been performed for a precessing jet model of SS433.
A precessing jet was modelled using relativistic hydrodynamic code (PLUTO).
