"The Simons Observatory: cosmology from the microwave sky"

The Simons Observatory (SO) is a new cosmic microwave background experiment being built in the Atacama Desert in Chile, due to begin observations in the early 2020s. SO will measure the temperature and polarization anisotropy of the cosmic microwave background using 60,000 detectors measuring the sky in six frequency bands. The observatory will have three 0.5-m telescopes and one 6-m telescope. I will describe the scientific goals of the experiment: to characterize the primordial perturbations that were imprinted in the early universe, to measure the mass of neutrino particles and the number of relativistic species, to test for deviations from a cosmological constant, to improve our understanding of galaxy evolution, and to constrain the duration of cosmic reionization.  I will focus in particular on the way in which we will be searching for gravitational waves from the primordial universe, and how we will seek to measure the neutrino mass scale.
