Early Universe is where particle physics and astrophysics meet. In this course, we introduce the standard cosmology, its deficiencies, and its connection to particle physics. It will cover inflation, Big-Bang nucleosynthesis, dark matter, baryogenesis, and limits on various scenarios beyond the standard model physics.
