Volume rendering of a test simulation of the EAGLE project (astro.ljmu.ac.uk/~astrcrai/eagle). The intensity corresponds to the density of cosmic gas, whilst colour encodes the mass fraction of the gas comprised of heavy elements (or 'metals', to astronomers), which are synthesised in supernovae. The volume is 25 cMpc across, with periodic boundary conditions, and was evolved with a version of the GADGET-3 TreePM-SPH code adapted specifically for Eagle. The simulation was run and visualised on the COSMA-5 supercomputer at Durham University (UK), by the EAGLE simulation collaboration. The visualisation was created by Rob Crain (Leiden Observatory, NL) and Jim Geach (Herts University, UK) using their Typhoon toolkit.
