Our approach is driven by scientific questions, and the techniques we use depend on the nature of each investigation. We rely on numerical simulations to understand the physical processes that shape our universe. The results of numerical simulations are compared with observations, with the dual aim of improving the models and generating predictions that can be tested through observations. Astrophysics is currently in an era of extraordinary observational facilities that will challenge our understanding of the universe, and numerical simulations of galaxy formation are a powerful tool to face these challenges.
