DescriptionThe evolution of the universe is based on the idea of gravitational instability, whereby initial tiny fluctuations in the density of the Universe grew under the influence of gravity to form the large-scale gravitational structures we see around us today. These structures bend the trajectories of Cosmic Microwave Background photons through gravitational lensing, distorting its primordial polarization and converting divergent polarization patterns (E-modes) into curled polarization patterns (B-Modes). Imaging the lensing-generated B-modes, the POLARBEAR telescope will be able to shed light on all the components of the Universe influencing structure formation, such as neutrino mass and dark energy.
