Description
I will review the hierarchical evolution of voids, discussing how they build up the void population via the processes of merging and collapse. On the basis of the Multiscale Watershed Void Finder we investigate the systematics of void evolution in adhesion models of structure formation. Subsequently, we follow the evolution of walls, filaments and haloes in the interior of void regions in the high-resolution LCDM CosmoGrid simulation. The results will be connected to the filamentary void galaxy configuration VGS31 in SDSS. Finally, we turn towards the structure of the Local Void, and follow its dynamical evolution on the basis of an adhesion-based reconstruction of the Cosmic Web in the local Universe.
