TL;DR: It is shown that baryon-induced features in the initial conditions of the Universe are reflected in distorted form in the low-redshift galaxy distribution, an effect that can be used to constrain the nature of dark energy with future generations of observational surveys of galaxies.

TL;DR: In this article, the authors investigate the coupled formation and evolution of galaxies and their embedded supermassive black holes using state-of-the-art hydrodynamic simulations of cosmological structure formation.

TL;DR: The first systematic comparison study of thirteen different void finders constructed using particles, haloes, and semi-analytical model galaxies extracted from a subvolume of the Millennium simulation is presented in this paper.

TL;DR: In this article, the authors investigate the distribution of matter between neighbouring large haloes whose masses are comparable to massive clusters of galaxies and identify a total of 228 filaments between neighbouring clusters.

TL;DR: In this paper, the formation and evolution of voids in the dark matter distribution using various simulations of the popular A cold dark matter cosmogony was studied, where voids were identified by requiring them to be regions of space with a mean overdensity of -0.8 or less -the equivalent of using a spherical overdensity group finder for haloes.
