This image is associated with a paper entitled "Cluster Winds Blow Along Supercluster Axes" which discusses cluster structure . The upper image is a combined ROSAT false-color X-Ray image of hot gas in the cluster combined with VLA image of the jets found in the cluster. They appear to be blown by a wind, which in our study we found was usually aligned with nearby clusters (green dots in the plot below, in which the inset cluster is not to scale--it's actually about ten times smaller).
The next series of images in this directory are the results of a series of N-body experiments. Each image is the final two-dimensional density field. The 2D density field is equivalent to a slice through a 3D Einstein-deSitter universe. The images differ the initial conditions which were used to start the evolution. The colors indicate the density; black represents the lowest density while red represents the highest densities in the simulation, on a logarithmic scale.
This first image corresponds to what is generally believed to be a good approximation to the real universe on large scales.
This next image corresponds to what the structure would have looked like on smaller scales ( roughly on the scale of a galaxy) around the period of galaxy formation.
