Research Abstract

We performed precise measurements of the polarization of the cosmic microwave background, which is "the oldest light" emitted right after the birth of the universe. The observations were carried out for more than 2 years using the QUIET telescope located at the altitude of 5080m in Atacama, Chile. We successfully measured the E-mode polarization with the 2^<nd> best precision so far reported. The result was consistent with the expectation from the standard cosmology model. We also searched for the B-mode polarization predicted by inflation theories, and obtained the 2^<nd> best upper limit obtained so far.
