*Large Scale Structure and the Dark Energy Survey*

The striking discovery that the Cosmic expansion is not slowing down but
accelerating has established as one of the puzzles in Cosmology sparking
large observational campaigns across cosmic time to map the Large Scale
Structure and geometry of the Universe. The Dark Energy Survey is perhaps
the largest operating survey spanning 5000 deg2 up to redshift one,
measuring ~ 300 million galaxy positions and shapes, the light-curves of
few thousand supernovae, and the masses of tens of thousands of galaxy
clusters. In this talk I will review the probes that these surveys use to
test our cosmological model, such as galaxy clustering and weak lensing,
discussing current constrains and their implications, including the latest
cosmological results from the first year of DES observations.
