Unit 3048: Astrophysical Processes and Cosmology

1. Introduction to Astrophysical Processes

• Overview of astrophysics
• Celestial objects: stars, planets, galaxies, nebulae
• Energy generation in space: nuclear fusion, radiation
• Behavior of matter in space: plasma physics, magnetic fields

2. Stellar Evolution

• Star formation: molecular clouds and protostars
• Main sequence phase and nuclear fusion in stars
• Post-main sequence evolution: red giants, supergiants
• End-states of stars: white dwarfs, neutron stars, black holes
• Supernovae: types and mechanisms

3. Galactic Dynamics

• Structure of galaxies: spiral, elliptical, irregular
• Galaxy formation and evolution
• Galactic interactions and mergers
• Role of dark matter in galaxy dynamics
• Rotation curves and dark matter evidence

4. Cosmology and the Big Bang Theory

• The universe at large scales
• Historical development of cosmology
• Big Bang theory: origin, timeline, and evidence
• Cosmic microwave background radiation
• Expansion of the universe and redshift
