“Reconstructing the history of our Universe with projected Large-Scale Structure”
The last twenty years have seen a tremendous growth in the quantity, variety, and quality of multi-wavelength astronomical observations of the large-scale structure (LSS). Our ability to observe different properties of the same structures now allows us to reconstruct the evolution of the matter density fluctuations over billions of years of cosmic history, and over a wide range of scales, spanning several decades. In this talk I will review current advances in our understanding of the LSS from the joint analysis of different probes, and what they have revealed about our Universe’s history and origin. Along the way, I will also highlight some of the observational, numerical, and modelling challenges that the field faces if we are to fully exploit the forthcoming “Stage-IV” LSS experiments for fundamental physics.
