Our Local Universe may well be the best-observed volume of the Universe, but it is also a disruptive factor when it comes to observe beyond it. Using positions and peculiar velocities of more than 8,000 galaxies from the second Cosmicflows catalog, we are now able to reproduce in Constrained Local UniversE Simulations the full three dimensional distribution of matter in the observed nearby...

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...

The Dark Energy Survey (DES) is a galaxy photometric survey designed to study the properties of the Dark Energy using four main cosmological probes: galaxy clustering on large scales, weak gravitational lensing, galaxy-cluster abundance, and supernova distances. During the northern fall of 2012 the DES collaboration installed and commissioned DECam, a 570 mega-pixel optical and near-infrared...
