Four example slices of the 2048 × 2048 resolution models. Plotted is a passive scalar where light yellow indicates fluid that originally belonged to the SN ejecta and dark purple indicates the surrounding material. Scales here are normalized by the radius of the shock. The dominant angular mode θ ₀ for each model is traced out by the dotted lines. This opening angle roughly traces the width of the Rayleigh–Taylor fingers.
