A team of astronomers from the Dutch University of Leiden and the British one of Durham created a simulation of the universe called EAGLE (Evolution and Assembly of Galaxies and their Environments). This project is run by the Virgo Consortium which has exactly the aim to produce cosmological simulations using supercomputers. The result, published in the January 2015 edition of the journal “Monthly Notices from the Royal Astronomical Society”, reproduces faithfully the evolution of the galaxies from a very uniform starting point.
