About the Course:
This is an introductory course on Cosmology. The aim is to understand how physicists try to address the whole Universe as a physical system. The question of the beginning, the evolution and the end of the Universe will be touched in this course. The interplay of the Physical laws and Cosmic evolution will be studied and we will discuss the question of the what the Universe is made of?
The topics that will be covered or touched are as below:
1) Historical Perspective to Cosmology
2) Cosmological Principle - Multiwavelength Astronomy
3) The Expanding Universe and Newtonian Cosmology
4) The Evolution of Universe
5) Baryons, Radiation, Dark Universe
6) Thermal History
7) CMB
8) Large Scale Structure
