Enrique Gaztanaga

Summary

My expertise is in the area of Cosmological models and the Large Scale Structure (LSS): the distribution of galaxies, radiation and matter on the largest observable scales. In particular: i) how light from galaxies traces the underlaying mass: theory, measurements and simulations ii) comparison of perturbation theory to data and simulations: development of novel tools, iii) measurement and modelling of Galaxy-CMB cross-correlation techniques iv) measurements and modelling of higher order correlation function and Baryon Acoustic Oscillations (BAO), v) interpretation of cosmological models and the laws of Physics.
