The image below is a slice through the simulation volume, with the intergalactic gas colour coded from blue to green to red with increasing temperature. Modelling these aspects accurately is key to produce a virtual universe that looks like the real one. The devastating effects of these explosions can be directly seen in starburst galaxies such as M82 and massive galaxies such as those in the Perseus cluster. However core collapse supernovae, exploding massive stars, and AGN (Active Galactic Nuclei), bursting supermassive black holes, severely limit what fraction of the gas forms stars. Gas falling into these dark matter structures cools and forms stars: this is how galaxies form. Crucial parameters are the density of dark matter - which allows structures to grow, baryonic matter - the gas from which stars form, and the cosmological constant - responsible for cosmic acceleration.ĭark matter enables structures like galaxies to form, even while the Universe is expanding rapidly. The simulation starts when the Universe is still very uniform - no stars nor galaxies had formed yet - with cosmological parameters motivated by observations by the Planck satellite of the cosmic microwave background. This website contains downloadable images and movies, many of which are located in Highlights or Downloads. This is large enough to contain 10,000 galaxies of the size of the Milky Way or bigger, enabling a comparison with the whole zoo of galaxies visible in the Hubble Deep field for example. This computer calculation models the formation of structures in a cosmological volume, 100 Mega parsecs on a side (over 300 million light-years). Welcome to the EAGLE Project What is the EAGLE project?ĮAGLE (Evolution and Assembly of GaLaxies and their Environments) is a simulation aimed at understanding how galaxies form and evolve. ![]()
