| Research Abstract |
Current cosmological observations are so precise that they give us a lot of information and profound insight on the evolution of the Universe from the very early epoch to the present, as well as the nature of dark components such as dark matter and dark energy. In this research project, we have investigated various aspects of cosmological density fluctuations, in particular, non-Gaussianity of primordial fluctuations. We have studied various models of the early Universe, focusing on its observational signatures for non-Gaussianity, which would give many implications for understanding of the evolution of the Universe and particle physics models.
