Snapshot of the Flagship galaxy simulation. Top: False colour image showing a slice of 3.800 h⁻¹ Mpc width and 500 h⁻¹ Mpc height (roughly 0.3% of the total volume) of the full light-cone Flagship mock. Central galaxies are coloured in green and satellites in red, where filaments from the large-scale structure are seen in great detail. Bottom left: Zoomed-in section with the local Universe (z = 0). Bottom right: Zoomed-in fraction of the furthest galaxies (z = 2.3). The simulation is a 3-dimensional sphere and the dark area at the right of the image corresponds to the end of the simulation where no dark matter particles are simulated.
