Description
To study the dynamical evolution and connectivity of the cosmic web, we describe our adhesion model of cosmic structure formation based on Voronoi and Delaunay tessellations. Subsequently, we describe how a phase-space analysis allows us to assess the growth of structural complexity in terms of the emergence of singularities and caustics. We indicate how the connections that emerge out of this hierarchically evolving weblike network can be quantified in terms of persistent homology. W ith our Nexus multiscale morphology formalism we explore the gravitational influence of structural components of the cosmic web. Filaments represent the most outstanding force in the Universe. However, it is the dynamical influence of voids that determines the pattern and connectivity of the cosmic web.
