英文摘要
We investigate statistical nature of fluctuations from the homogeneous isotropic Universe, such as temperature anisotropies of cosmic microwave background and large scale structure of the Universe, in particular, deviation from Gaussian distribution, i.e., non-Gaussianity. We study non-Gaussianity in temperature anisotropies caused by primordial magnetic fields and set a constraint from observations. We also study the influence of fluctuations with non-Gaussianity with curtosis on structure formation of the Universe.
