Density slices through the central plane of the SNR #22 at various points in time for each model. Arrows are depicting the velocity field in the co-rotating center-of-mass frame of the local ISM. The various timescales correspond to different points in time for the different models. Red and blue arrows in the top-right corner of each panel indicate the directions of the galactic rotation and the galactic center, respectively. The dashed orange contour corresponds to the surface where Z_ej = Z_{thr, low}, while the solid contour corresponds to Z_ej = Z_{thr, high}. Since the various timescales are undefined for the model no_expl, we are using the same times as model N10. The SNe explode into a fairly homogeneous ISM, with a slowly collapsing, slight overdensity right where the SNe explode. At similar evolutionary stages the SNR is about twice as large in N10 compared to N1, with very similar geometry; Spheroidal with a slight elongation in the direction of rotation. On the other hand, the geometry in the model N1×10 qualitatively differs from the other models, with an elongated cavity normal to the rotational direction, due to the elliptical orbit (v_R ∼ 20 km/s) of the explosion site. Only in the model N1, after 10 Myr a dense cloud, aligned with the SNR is forming in the center as predicted by Romano et al. (2024a).
