Galactic Gas

Caption

Two stills of galactic gas from the Feedback in Realistic Environments simulation. Represented here is a Milky Way mass halo, with colors denoting different densities. Magenta shows cold molecular/atomic gas (T < 1000 K). Green shows warm ionized gas (10e4 < T < 10e5 K). Red shows hot gas (T > 10e6 K). Left box is at high redshift, and the right is at present day. A more relaxed, well-ordered disc has formed, with molecular gas tracing spiral structure, and a halo enriched by diffuse hot outflows.
