Studying Galaxy Formation with Modern Cosmological Simulations

Numerical simulations have been playing an increasingly large role over the past two decades in developing our understanding of cosmology and galaxy formation.  Modern cosmological simulations evolve large volumes of the Universe from soon after the Big Bang until the present day while reproducing realistic galaxy populations.  We use these simulations as “numerical experiments” to probe the impact of various physical effects on the growth of galaxy populations that otherwise cannot be tested in earth-based laboratories or through extragalactic observations.  In this talk I will outline the approach that is used to build cosmological simulation codes, identify areas of unique progress made in recent years, discuss some major outstanding questions, and explore the computational approaches and resources that are required.
