“Frontiers in Optical and CMB Survey Cosmology”

 

Observations of the cosmic microwave background (CMB) and the galaxy-filled sky provide images of the universe at its various stages that are sensitive to its physics from the earliest moments to recent times. These observations are key to expanding our understanding to the physics of inflation, neutrinos, dark matter, and dark energy—some of the most mysterious terrains in physics today. We will present results from current CMB and optical surveys—the South Pole Telescope & BICEP/Keck Array and the optical Dark Energy Survey, respectively—whose unprecedented sensitivities enable us to stringently test the standard cosmological model and constrain new physics. We will discuss their current limitations due to calibration uncertainty and confounding astrophysical effects. To conclude, we will look forward to the bright future of optical, CMB, and joint cosmological experiments that will be performed by the Vera C. Rubin Observatory's Legacy Survey of Space and Time and the CMB-S4 experiment.
