Cosmic Microwave Background: Observations and Implications

This lecture covers the Cosmic Microwave Background (CMB), its origin, anisotropies, and statistical assessment. It explores the cosmological tests using CMB, lensing mass models, and the history of the early Universe. The presentation delves into the Big Bang Nucleosynthesis, the CMB's role in probing the Universe, and the measurements from experiments like COBE, WMAP, and Planck.
