What is ASTR2000 about?

This unit begins with an overview of basic cosmology, applying Newtonian physics to understand the observational consequences of the hot Big Bang and the theory of inflation, from the expansion of the Universe to the existence and properties of the Cosmic Microwave background and the abundances of light elements. The physics of stars is then explored in some detail, from stellar structure to the nuclear reactions that produce energy, showing that stellar nucleosynthesis and supernova explosions generate all the heavy elements in the universe. Stellar life cycles are then investigated, from star formation to stellar end products (white dwarfs, neutron stars and black holes), exploring in detail the use of star clusters (both open and globular) as evolutionary microcsoms. Galactic structure and dynamics are then discussed, leading into an exploration of some key issues in modern astrophysical research, such as dark matter problem. Finally, the understanding of Galactic structure and accretion physics gained in this unit is applied to explore the nature of quasars, the most luminous objects in the Universe that are powered by super-massive black holes in the cores of galaxies.
