  2. An inflowing shockwave (v = 1000 km/s) impacts an spherical cloud with a core overdensity of 1000 with respect to the background medium. As the inflowing gas blows past the cloud the material and material is stripped off, there is a high amount of vorticity generated. By rendering enstrophy, we see the formation of vortex tubes. This movie runs for ~4 "cloud-crushing" times (in this case, ~400 years). The cloud is also rotated as time is advanced.

  3. A rotation of a dataset from an simulation in which 15 individual clouds are simultaneously crushed by an inflowing shock. The contours are of the gas density. This was made using the fisheye camera renderer in yt (yt-project.org). The fisheye camera allows this movie to be shown on a planetarium dome. Specifically, this will be shown on the Adler Planetarium in Chicago, as part of the 2012 yt workshop. The simulation was performed using Enzo and carried out on the NASA supercomputer, Pleiades.
