The Simons Observatory: A Deep Survey of the Millimeter-wave sky to Search for the Origins and the Evolution of our Universe Over Cosmic Time

Large scale millimeter-wave surveys of the sky with arcminute resolution will produce rich new datasets addressing a wide range of pressing science questions. The next generation of Cosmic Microwave Background (CMB) instruments, including the Simons Observatory (SO) and CMB-S4, will probe the origins and evolution of the universe and search for primordial gravitational waves and new light particles. They will also serve a broad scientific community seeking to understand topics such as galaxy evolution, the transient universe, the role of magnetic fields in the interstellar medium in our Galaxy, and the search for Planet 9 in the Solar System. I will review the evolution of CMB measurement from Chile, the Simons Observatory goals and status, and plans for the future of CMB in Chile.
