JWST Science Simulations: Galaxy Formation

This visualization shows small galaxies forming, interacting, and merging to make ever-larger galaxies. This 'hierarchical structure formation' is driven by gravity and results in the creation of galaxies with spiral arms much like our own Milky Way galaxy. The Adaptive Mesh Refinement (AMR) simulation generated from ENZO code for cosmology and astrophysics was developed by Drs. Brian O'Shea and Michael Norman. The AMR code generated 1.8 terabytes of data and was computed at NCSA. AVL used Amore software (http://avl.ncsa.illinois.edu/what-we-do/software) to interpolate and render 2700 frames (42 gigabytes of HD images). The simulation spans a time period of 13.7 billion years. This visualization provides insight into the assembly and formation of galaxies. James Webb Space Telescope (JWST) will probe the earliest periods of galaxy formation by looking deep into space to see the first galaxies that form in the universe, only a few hundred million years after the Big Bang.

The Advanced Visualization Laboratory (AVL) at the National Center for Supercomputing Applications (NCSA) collaborated with NASA and Drs. Brian O'Shea and Michael Norman to visualize the formation of a Milky Way-type galaxy.
