Omschrijving The large scale distribution of galaxies and matter defines an intricate network of dense compact clusters, filaments, sheets and large voids. This web is one of the main fossils of the cosmic structure formation process, and mining its information content has become an important cosmological activity.

In this course we will start with an observational overview, based on galaxy redshift surveys, quasar absorption lines, and gravitational lensing studies. Subsequently we will treat extensions of the Zel'dovich formalism, in particular adhesion theory. We will zoom in on the dynamical evolution of both clusters and voids. Armed with this insight, we will be able to adress the theoretical framework of Cosmic Web theory, including extensions of the Press schechter theory involving anisotropic collapse of clusters and other features and the hierarchical evolution voids. Two lectures will be devoted to the analysis tools that have been developed over the past decade to analyze complex spatial patterns. These include feature measures, Minkowski functionals, Morse theory and the skeleton, the Multiscale Morphology Filter, and tessellation-based tools for detecting filaments and voids. One particular example of their application will address the question of whether we can find remnants of the galaxy rotation origin in their alignment with filaments and walls. In the final week, we will turn to the study of the gaseous web, both the Lya forest and the WHIM.
