Abstract Whole-sky surveys are revolutionizing the way research is conducted in cosmology. In order to extract the maximum scientific output, standard methods used in the analyses need to be refined so systematic errors are not included. The Dark Energy Survey will map the sky in the optical bandwidth and will detect 200 million galaxies and 100 thousand galaxy clusters, aiming at providing a better comprehension of dark matter and dark energy. In this project we intend to use three groups of observables, namely, galaxy clusters, large scale structure and cosmic voids, to improve our knowledge of these mysterious components. A thorough characterization of the tests will be performed searching for systematic errors through realistic simulations performed by the survey. Followed by that we will apply the tests to data thereby providing constraints to the cosmic concordance LCDM model as well as alternative dark energy models and modified gravity theories. (AU)
