Density projection. Projection of the density of the SNR (ejecta and shocked ISM) according to the three spatial axes (columns) taken 450 yr after SNR explosion. Here, four different situations are represented (one per line). The ‘no turbulence’ case corresponds to the simulation with a uniform ISM. The ‘low turbulence’ case includes turbulence and uses the lower-σ value (0.05). This case does not differ significantly from the ‘no turbulence’ one. Both ‘turbulence 1’ and ‘turbulence 2’ employ a turbulent ISM with σ = 0.5, but each uses a different set of random phases. The BW appears wavy in these cases, which is closer to the morphology of the BW observed in Tycho.
