Large-scale structures of the Universe: physics, phenomenology, statistics

Abstract

In this series of lectures, we seek to describe the evolution of the cosmic large-scale structure. We will discover the cosmic web - the large-scale skeleton of matter traced by galaxies. It arises from the interplay of the gravitational pull of dark matter and the expansion driven by dark energy. Major large-scale galaxy surveys map the distribution of matter and galaxies across most of the sky, spanning over 10 billion years of cosmic history. I will guide you through some of the principles and challenges behind predicting the statistical properties of the matter and galaxy distribution in vast cosmic volumes. In particular we discuss the underlying nonlinear physics and resulting non-Gaussian statistics that need to be predicted to extract fundamental physics from observational data.
