Scientific simulations: IllustrisTNG Single Galaxy Formation

This video is an example of a powerful scientific simulation that helps cosmologists understand the mechanisms of galaxy formation and test out different theories about physics and cosmology. Credit: TNG Simulations (http://www.tng-project.org/media/) Description from TNG project: "Formation of a single galaxy, tracked through time from high redshift until the present day. This relatively "average" TNG50 galaxy will be just slightly less massive than our own Milky Way at z=0. We include a large-scale view (lower left), and zoomed in views of the central gas and stellar structures (lower right), while the main panel shows projected gas density. At z=1.5 we pause and rotate around the system, showing in order: gas metallicity, gas velocity field, and H-alpha luminosity, before continuing. What is a small dwarf at high redshift (108.3 solar masses in stars at z=4) transitions, at late times, into a large stable disk with a quasi-steady star formation rate of a few solar masses per year."
