Resumen:
Superclusters are the largest gravitationally bound systems in the
Universe. These structures are not presently virialized, so the
application of theoreti- cal arguments in their identification is not
straightforward. Luparello et al., (2011) present an identification
method and establish the values of the pa- rameters in order to ensure
that superstructures in the present Universe will evolve into virialized
structures. In this work we define and characterize the largest
structures in the Universe, in the framework of the cosmological model
CDM. We briefly describe the Future Virialized Structures (FVS)
identification method applied to the seventh data release of the Sloan
Digital Sky Survey (SDSS-DR7, Abazajian et al., 2009) in the redshift
range 0.04 < z < 0.12 and present the main properties of the FVS
catalogue.
