Description

The Q/U Imaging ExperimenT (QUIET) is a ground-based radiometer array designed to measure the polarization of the Cosmic Microwave Background (CMB) radiation. The polarization of the CMB can be decomposed into a curl-free component, or E-modes, and divergence-free component, or B-modes. Previous observations for the E-modes as well as temperature anisotropy of the CMB have been used to constrain the cosmological parameters that model the history of our universe. On the other hand, the B-modes are uniquely sensitive to primordial gravity waves from the inflationary epoch. The B-modes have not been observed yet. QUIET and other current and future experiments are aiming for the detection of the inflationary B-modes. In this presentation, I will talk about the instrumentation, observation strategy as well as the current status of the analysis, and discuss about future upgrade of QUIET.
