Galaxies: Formation, Evolution, Phenomena

Our understanding of physics at very early Universe, as early as 10 −35 s after the Big Bang, relies on the scenario known as the inflationary cosmology. Inflation predicts a particular polarization pattern in the cosmic microwave background, known as the B -mode yet the strength of such polarization pattern is extremely weak. To search for the B -mode of the polarization in the cosmic microwave background, we are constructing an off-axis rotating telescope to mitigate systematic effects as well as to maximize the sky coverage of the observation. We will discuss the present status of the GroundBIRD telescope.
