我们对宇宙早期物理学的理解，早在大爆炸后 10−35 秒内，就依赖于被称为暴胀宇宙学的场景。暴胀预测了宇宙微波背景中的特定偏振模式，称为 B 模式，但这种偏振模式的强度极其微弱。为了寻找宇宙微波背景中偏振的 B 模式，我们正在建造一台离轴旋转望远镜，以减轻系统效应并最大化观测的天空覆盖范围。我们将讨论 GroundBIRD 望远镜的现状。
Our understanding of physics at very early Universe, as early as 10−35s 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 theB-mode yet the strength of such polarization pattern is extremely weak. To search for theB-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.
