The First Light And Re-ionisation Epoch Simulations (FLARES) is a novel suite of hydrodynamical cosmological zoom simulations formed by re-simulating a range of environments from a large parent volume. This allows us to simulate much larger effective volumes than possible with a traditional periodic box. This makes FLARES ideal for studying massive/rare objects such as AGN and bright star forming galaxies that might be absent in smaller periodic box simulations like the EAGLE reference simulation.

In this talk I will first present the properties of AGN in FLARES showing both their physical properties and their contribution to the light emitted from galaxies. Using a set of matched simulations with no AGN I will also show the impact of AGN on galaxies in the Universe. Following from this I will use FLARES to make predictions for the Euclid DEEP survey, which will allow us to identify the rarest and brightest sources in the early Universe, providing a new test of galaxy formation physics. Euclid DEEP will enable the constraining of the extreme bright-end of the UV luminosity function deep into the EoR (5 z 9).
