The Tiamat simulations are a suite of large collisionless N-Body simulations upon which DRAGONS is built. The primary asset setting Tiamat apart from most other large simulation programs is its high density of simulation outputs at high redshift (100 from z=35 to z=5; roughly one every 10 Myrs) enabling the construction of very accurate merger trees at an epoch when galaxy formation is rapid and mergers extremely frequent. We use Tiamat to analyse the dynamical evolution of galaxies at high redshift, drawing comparisons to low-redshift results from other simulations.
