Chaos in a cosmic shock
The amplitude of the density perturbation grows as it propagates downstream (from left to right) across a C-type shock in a typical environment of star-forming clouds. The growth arises from an unstable mode driven by the ion-neutral drag, i.e., the drag instability, which can lead to a chaotic shock structure.
