Description
The striking discovery that the expansion of the Universe is not slowing down but in fact accelerating has turned into one of the main mysteries in Physics today, with explanations that range from new repulsive forces, as the dark energy, or the failure of Einstein's General Relativity (GR). Understanding this puzzle, and others such as the dark matter or the physics of Inflation, has set the programme for the next decade of Observational Cosmology. The goal is to undertake large astronomical surveys that, by scanning millions of galaxies across cosmic time, will study the origin and evolution of the Large Scale Structure of the Universe. In this talk I will review which are some of the probes that these surveys use to test GR, such as galaxy clustering and weak lensing, discussing current constrains and their implications. And particularly the perspective from ongoing and future surveys, such as the Dark Energy Survey (DES) or the ESA/Euclid satellite.
