This article is based on the results presented in Yaryura et al. (2012, MNRAS, 426, 708), where the clustering properties of galaxies is analyzed as a function of their large-scale environment. In order to characterize the environment on large scales, we use the catalogue of future virialized superstructures (FVS) by Luparello et al. (2011, MNRAS, 415, 964) and separate samples of luminous galaxies according to whether or not they belong to FVS. The correlations have similar amplitudes at scales r ≤ 1 h^{-1} Mpc. We have performed a similar analysis using a semi-analytic implementation in a ΛCDM cosmological model, where we found that the cross-correlation functions depend on the large-scale structures in a similar way to the observations.
