Query: Measuring the Cosmic Web   A quantitative study of the clustering properties of the cosmic web as a
function of absolute magnitude and colour is presented using the SDSS Data
Release 7 galaxy survey. Mark correlations are included in the analysis. We
compare our results with mock galaxy samples obtained with four different
semi-analytical models of galaxy formation imposed on the merger trees of the
Millenium simulation. The clustering of both red and blue galaxies is studied
separately.
