Resumen:
We introduce a new method for the identification of galaxy systems in redshift surveys based on the halo model. This method is a modified version of the K-means identification algorithm developed by Yang (2004). We have calibrated and tested ouralgorithms using mock catalogs generated using the Millennium simulations (Springel2005) and applied them to the NYU-DR7 galaxy catalog (based on the SDSS datasets).
