The Cosmic Microwave Background

This lecture covers the history of the Universe, from the Big Bang Nucleosynthesis to the Cosmic Microwave Background (CMB). It explores the mass measurements of objects, the CMB's role in probing the early Universe, and the statistical assessment of the CMB. The presentation delves into the recombination history of Hydrogen and Helium, the anisotropies in the CMB, and the cosmological tests conducted using the CMB. It also discusses the experiments like COBE and WMAP, which played a crucial role in understanding the CMB. The lecture concludes with insights into the Planck mission and its cosmological results.
