Observation of Cosmic Microwave Background Polarization with BICEP
Background Imaging of Cosmic Extragalactic Polarization (BICEP) is a bolometric polarimeter that has been optimized to target the B-mode of the cosmic microwave background (CMB) polarization at degree angular scales, which is a sensitive probe of the energy scale of inflation. The instrument's...
