Understanding the CMB: from inhomogeneities to that plot you know
Date:
The Cosmic Microwave Background (CMB), the frozen photons from when the Universe was approximately 350 thousand years olf, is a gold mine for cosmologists. We have used it to learn about how the Universe started, what are its components, and how it might end. In this talk, I will give a brief overview of where does the CMB comes from, what makes it special, and how to extract information from it.
