Cluster Simulations on the PSC Cray T3E
A process somewhat analogous to that of the alleged formations of the
universe, time and times ago, was observable. The bustling swarm had swept
the sky in a scattered and uniform haze, which now thickened to a nebulous
centre: this glided on to a bough and grew still denser, till it formed a
solid black spot upon the light.
- Thomas Hardy, Far From the Madding Crowd
A simulation of a cluster of galaxies using the parallel treecode on the
Cray T3E at the Pittsburgh Supercomputing Center.
The core of the cluster is shown here 7.5 billion years after
the Big Bang. The cluster center is dominated by a massive, bright elliptical
galaxy which forms early on through the runaway merger of several
galaxies and closely resembles the bright central galaxies seen in real
galaxy clusters. Many of the disks show signs of disturbance brought on
through interactions with other galaxies and the bright central galaxy.

The first 3 movies cover the evolution of the cluster over 10 billion
years and the last 2 are rotations of the cluster at z=0.35 and z=0.
The long side of the box is 1.5 Mpc in length. If you're using xanim, I
find that "xanim -Cn +CF4" gives the best results.
