Description:

In Cosmology, most of the information comes from observing the small departures from homogeneity that characterize our universe: they tell us about its current matter content as well as about its initial conditions. In this regard, Cosmological Large-Scale Structure surveys will probably offer the next leading source of information. I will present how particle-physics-inspired field-theoretic techniques have allowed us to formulate a theory that accurately describes the dynamics of the universe at long distances, and how this has already allowed us to achieve major improvements in our capability of extracting information from these surveys, for example shedding some light on the so-called Hubble tension.
