Summary
Supernovae and astrophysical jets are two of the most energetic and intriguing objects in the universe. An interaction between these two extreme phenomena is believed to be present in the case of the W50-SS433 system: a jet launched from the microquasar SS433 (an X-ray binary) located inside a supernova remnant, W50. Observations have revealed a unique morphology of the remnant, attributed to the presence of the jet. Motivated by these studies, we performed full 3D relativistic hydrodynamic simulations to better capture the interaction between the remnant and the jet. The output was used to create emission maps by post-processing them with a radiative transfer code. We verify again (in 3D) that the stratification of the ambient medium is important to reproduce the asymmetric shape of W50. The full precession of the jet is now implemented; its effect is important before collimation but not evident compared to a straight outflow on larger scales. Radio maps quantitatively agree with actual observations of W50, with further improvements needed to correctly capture the intensity distribution of the remnant.
