Abstract:
The concordance model of cosmology has been able to accurately reproduce the main cosmological observations for many years. However, the nature of its two main components, dark matter and dark energy in the form of a cosmological constant, remains still unknown. Moreover, the latest cosmological analyses start to show some possible deviations with respect to this concordance model. In this talk I will provide a brief overview of current cosmological constraints that try to shed some light on the dark sectors of the Universe, paying special attention to galaxy surveys. I will then introduce the European Space Agency Euclid mission, and finish by presenting the forecast constraints on dark energy, dark matter, and gravity using the upcoming Euclid data.
