Description

The Dark Energy Survey is one of the largest ongoing survey probing the late universe, specially through galaxy clustering and weak gravitational lensing. The data from the first year of DES observations were used to constrain the LambdaCDM model in 1708.01530, combining clustering and weak lensing measurements from the same experiment for the first time. We used this combination of data to constrain extended cosmological models considering a time varying dark energy equation of state or deviations from general relativity, among others. I will present these new results, specially focusing on the extensive analysis we performed to treat systematics.
