Resumen:
We study superstructures on the SDSS-DR7 spectroscopic galaxy catalogue, by constructing a smoothed density map and appliyng minimum threshold and conectivity criteria. For several threshold values between 4 and 8 times the mean luminosity density, we contrast results with a Mock catalogue by comparing the multiplicity function. We then compute the supercluster lu- minosity function, and find that observed space density of superstructures is underpredicted by the standard cosmological CDM model.
