Dark-ages, Reionization And Galaxy-formation Observables Numerical Simulation


Smaug is a suite of gas hydrodynamic cosmological simulations of used to model galaxy formation at high redshift. The simulations include galaxy formation with strong, thermally coupled supernovae. These models produce enough UV photons to sustain reionization through a significant population of faint, unobserved, galaxies. This predicted population is consistent with extrapolation of the faint end of observed UV luminosity functions. We use these models to inform and calibrate the physics implementations in our Meraxes model.
