This course explores the computational simulations used in astrophysics and cosmology to understand the evolution of the Universe. The learning outcomes include gaining insights into cosmological structure formation, galaxy formation, and the dynamics of dark matter. Students will learn about N-body simulations, dark matter haloes, hydrodynamics, and sub-grid models for phenomena like supernovae and black holes. The teaching method involves a presentation on the history, techniques, and current state of simulations, with comparisons to observational data. This course is intended for individuals interested in astrophysics, cosmology, computational science, and the evolution of the Universe.
