Orbiting and Colliding Galaxies 3D Model
written by Robbie Mitchell
The Orbiting and Colliding Galaxies 3D Model is a three-dimensional extension of the Alar and Juri Toomres' 1972 supercomputer model of colliding galaxies. This model assumes that galactic centers are point masses and the orbiting stars do not interact with each other (the galactic cores interact with each other and the individual stars). Unlike the Toomres' model (and the Colliding Galaxies model by Christian and Lim), both galactic cores begin with a compliment of stars orbiting their respective cores. These stars start in a 3-D circular orbit about the center of each galaxy in one plane. When the two galaxies pass each other they produce the long spiraling tails.
The Orbiting and Colliding Galaxies Model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_comp_phys_colliding_galaxies3d.jar file will run the program if Java is installed.
