CMB Temperature Fluctuations

Temperature Fluctuations

Despite its uniformity, there do exist fluctuations in the CMB temperature on the sky. These are due to over/under densities in the early universe. In this section, we'll cover the physical mechanisms which create these observed cold and hot spots in the CMB and create our own map of the CMB with real data!
