The South Pole Telescope Project is built to observe the temperature and polarization of the cosmic microwave background at arcminute and larger scales. This provides information on the origin and history of the universe, with the project's main science goals including the properties of light stable particles (in particular neutrino mass and number), inflation, dark matter, dark energy, the dynamics of galaxy clusters, and the nature of the universe's first structures. The South Pole Telescope's current receiver, SPT-3G, began its science run in early 2018.
The Wilkinson Microwave Anisotropy Probe (WMAP) is a NASA Explorer mission measuring the temperature of the cosmic background radiation over the full sky with unprecedented accuracy. This map of the remnant heat from the Big Bang provides answers to fundamental questions about the origin and fate of our universe.
Ned Wright's Cosmology Pages. In the words of Professor Ned Wright: "Cosmology is the study of the origin, current state, and future of our Universe. This field has been revolutionized by many discoveries made during the past century. My cosmology tutorial is an attempt to summarize these discoveries. It will be "under construction" for the foreseeable future as new discoveries are made. I will attempt to keep these pages up-to-date as a resource for the cosmology courses I teach at UCLA."
