First Light And Reionisation Epoch Simulations (FLARES) II: The Photometric Properties of High-Redshift Galaxies

Understand

We present the photometric properties of galaxies in the First Light and Reionisation Epoch Simulations (FLARES).

• The simulations trace the evolution of galaxies in a range of overdensities through the Epoch of Reionistion (EoR).
• With a novel weighting scheme we combine these overdensities, extending significantly the dynamic range of observed composite distribution functions compared to periodic simulation boxes.
• FLARES predicts a significantly larger number of intrinsically bright galaxies, which can be explained through a simple model linking dust-attenuation to the metal content of the interstellar medium, using a line-of-sight (LOS) extinction model.
