Rotating views of an "organic" star-forming disc galaxy simulated with the EAGLE model, and two further realisations of the same system that have "genetically modified" initial conditions that yield earlier (GM-Early) or later (GM-Late) assembly.

The movie shows the dark matter halo, followed by the stars and star-forming gas in the central galaxy, at redshifts 0, 1 and 2.

The systematic adjustments to the halo assembly history have a dramatic effect on the properties of the central galaxy. Shifting the assembly to earlier times yields a quenched, spheroidal galaxy at the present day, while shifting the assembly to later times yields a more vigorously star-forming disc.
