The Genesis Theoretical Simulations

Large-scale super-computer models of galaxy formation are providing an ever increasingly detailed theoretical framework for interpreting observations.

We are:

  • Channelling Australian observational and theoretical expertise into new state-of-the-art cosmological simulations of galaxy formation and evolution that are directly constrained by our observations across cosmic time.
  • Tracking the birth, growth and ultimate fate of galaxies from the earliest epoch of galaxy assembly, through the Epoch of Reionisation to the present day and simulate the first stars, early Universe chemical enrichment, proto-galaxy formation, reionisation, galaxy growth through star formation and mergers, the build-up of angular momentum from the scales of galaxy clusters to star-forming regions within galaxies, the emergence and evolution of large-scale massive structures in the Universe, and the evolution of the material between galaxies.
  • Combining advanced physical galaxy modelling techniques with realistic 3D radiative transfer models to produce tailored theoretical models to create synthetic multi-wavelength datasets that can be used to directly interpret the observations from our major 3D surveys. The models will incorporate “zoom-in” re-simulations that will track the growth of targeted galaxies within the simulation in exquisite detail, allowing us to model the local galaxy population and the imprint of galactic history in the chemistry and structure of the galaxy population to compare directly with our 3D observations.
  • Cementing the observational programs across both themes, giving the theoretical backbone for the interpretation and analysis of our observational surveys. Synergistically, the models will provide predictions for the optical and radio surveys, and the results of the surveys will be used to constrain the models and yield more accurate simulations of galaxy formation and evolution. We will create this synergy by embedding theorists within observational nodes, with theorists and observers working together towards our scientific goals.
