Effectively, the universe’s baby picture is a CMB map. For decades, satellite missions like COBE, WMAP, and Planck have mapped this ancient radiation. But ground-based experiments like the ACT ...

In this section we will learn about the CMB data from WMAP (http://map.gsfc.nasa.gov/) and Planck (http://www.esa.int/Our_Activities/Space_Science/Planck). The goals ...

While the CMB’s near-perfect blackbody spectrum was first accurately measured three decades ago, and space missions such as WMAP and Planck have since revolutionised our understanding of the Universe ...

Precise measurements of CMB anisotropies can determine with a high degree of accuracy ... Previous experiments, such as the WMAP satellite, have supported a flat theory. The recent Planck release, ...
