TL;DR
This paper analyzes the clustering properties of the cosmic web using SDSS data, comparing observations with four galaxy formation models to understand how galaxy characteristics relate to large-scale structure.
Contribution
It provides a detailed quantitative comparison of galaxy clustering as a function of magnitude and colour, incorporating mark correlations and testing multiple semi-analytical models.
Findings
Red and blue galaxy clustering behaviors differ significantly.
Semi-analytical models show varying degrees of agreement with observed clustering.
Mark correlations reveal additional structure in galaxy distribution.
Abstract
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.
