Galaxy Spiral Arm Formation

Simulation: Elena D’Onghia and Mark Vogelsberger Harvard FAS Supercomputer Odyssey Visualization: Thiago ize Scientific Computing and Imaging (SCI) Institute - University of Utah Rendering of spiral arm formation consisting of 512 time steps of 100 million particles (stars) per time step. Rendered using the Manta Interactive Ray Tracer by making each particle a transparent sphere with transparency decreasing with increasing galaxy radius. Color map corresponds to particle speed.
