Title:
Cosmology via big data in Astrophysics
Abstract:
State-of-the-art observational surveys such as the one carried out by the EUCLID mission, BOSS, DES and forthcoming ones like LSST, HETDEX among others, will cover of the order of 10000 square degrees on the sky, with the primary science goal to unravel the nature of the physics responsible for the current accelerated expansion of the universe. The unprecedented and rich data provided by these surveys will make it possible to investigate fundamental physics (e.g. inflation, neutrino properties) and astrophysics (e.g. biasing, galaxy formation). The success of future large-scale galaxy surveys evidently requires a correct interpretation of their data. It is in this regard that we need to maximize the physics extracted from the data. I will briefly address some of the modern techniques devoted to carry on such tasks as well as how they get benefited from well-focused lines of astrophysical research (galaxy formation) in an attempt to have a complete picture of the galaxy distribution in the Universe.
