The FLARE simulations are a suite of high-resolution hydrodynamic simulations of galaxy formation and evolution using the EAGLE physics. The suite consists of a series of zoom resimulations of spherical regions selected at $z = 5$ from a $(3.2 \, \mathrm{Gpc})^3$ parent dark matter-only volume. We select a range of overdensities in order to study the environmental effect on high-redshift galaxy evolution. We also combine these resimulations in order to produce composite distribution functions, signficantly extending the dynamic range of the model over smaller volume, periodic simulations.

These simulations provide a valuable resource for studying galaxy evolution over the first 2 billion years of the Universe's evolution. We are working on predictions for a number of upcoming space-based observatories, such as JWST, WFIRST and Euclid. The latter two are of particular importance due to their wide-field capabilities, probing extreme environments at the extreme of the overdensity distribution. FLARES presents a unique resource for generating predictions for such surveys using the latest high-resolution hydrodynamic models.
