Colliding Galaxies Description

A free simulation featuring galaxy collisions Colliding Galaxies is an implementation of Alar and Juri Toomres' 1972 super computer model showing the formation of galactic bridges and tails under the assumption that galactic cores are point masses and that one galactic core is surrounded by 2D concentric rings of orbiting stars. The model assumes is that the stars (test particles) orbiting the galactic cores are non-interacting. When the two galaxies pass one another, tidal forces deform the star distribution into classic tidal features. Colliding Galaxies reproduces this result showing that there is a long curving tail and that only the outermost ring of stars is affected by its neighboring galaxy. A thin bridge is also formed and some of the stars are captured by the companion galactic core. Requirements: · Java 1.5 or later
