Lecture
This lecture covers the formation and evolution of galaxies, galactic dynamics, and the development of numerical tools in astrophysics. It delves into topics such as the standard model in cosmology, the Milky Way, stellar orbits, equilibria of collisionless systems, and the stability of collisionless systems. The course aims to teach how self-gravitating systems evolve under gravity forces, focusing on the backbone of galaxies. Throughout the lectures, students will explore various theoretical physics concepts, the galactic coordinate system, the structure of the Milky Way, and the total mass of the Milky Way. The instructor also provides insights into observational cosmology, galaxy surveys, and the virtual reality universe project.
