简介: |
I will describe the BICEP/Keck program, a series of South Pole-based experiments aiming to study inflation by measuring the B-mode polarization of cosmic microwave background radiation. The BICEP telescopes feature compact refractors and fully lithographic superconducting polarimeter arrays. In March 2014, BICEP2 reported a clear excess of B-mode polarization at angular scales corresponding to predictions from inflation. I will describe what this measurement means, the current uncertainties regarding foregrounds, and how we are going to follow this up with Keck and BICEP3,the current and next experiment in the series. |
