The Probe of Inflation and Cosmic Origins - Capabilities of a Next Generation $1B CMB Space Mission

We describe the capabilities of the Probe of Inflation and Cosmic Origins (PICO), a prototype for a next generation $1B-scale space mission. We present quantitative constraints on inflation in the presence of a wide range of foreground models. We demonstrate the value of a broad frequency coverage between 20 and 800 GHz, and of large sky coverage, which enables critical systematic cross-checks.
