Aims. We follow the evolution of galaxy systems in numerical simulations. Our goal is to understand the role of density perturbations on various scales in the formation and evolution of the cosmic web. Methods. We perform numerical simulations with the full power spectrum of perturbations, and with a spectrum cut at long wavelengths. In addition, we have one model, where we cut the intermediate waves. We analyse the density field and study void sizes and density field clusters in different… Expand

Towards understanding the structure of voids in the cosmic web
Our goal is to see how density waves of different scale combine to form voids between galaxy systems of various scale. We perform numerical simulations of structure formation in cubes of size 100 andExpand
Wavelet analysis of the cosmic web formation
According to the modern cosmological paradigm galaxies and galaxy systems form from tiny density perturbations generated during the very early phase of the evolution of the Universe. Using numericalExpand
Shell-like structures in our cosmic neighbourhood
Signatures of the processes in the early Universe are imprinted in the cosmic web. Some of them may define shell-like structures characterised by typical scales. We search for shell-like structuresExpand
SDSS superclusters: morphology and galaxy content
Context. Understanding the formation, evolution and present-day properties of the cosmic web and objects forming it is an important task in cosmology. Aims. We compare the galaxy populations inExpand
The Cosmic Web and galaxy evolution around the most luminous X-ray cluster: RX J1347.5−1145
In this paper we study large-scale structures and their galaxy content around the most X-ray luminous cluster known, RX J1347.5−1145 at z= 0.45. We make use of u*g′r′i′z′ Canada–France–HawaiiExpand
Sloan Great Wall as a complex of superclusters with collapsing cores
In the cosmic web, galaxy superclusters or their high-density cores are the largest objects that may collapse at present or during the future evolution. We study the dynamical state and possibleExpand
Supercluster A2142 and collapse in action: infalling and merging groups and galaxy transformations
Context. Superclusters with collapsing cores represent dynamically evolving environments for galaxies, galaxy groups, and clusters.Aims. We study the dynamical state and properties of galaxies andExpand
Galaxy Quenching from Cosmic Web Detachment
We propose the Cosmic Web Detachment (CWD) model, a framework to interpret the star-formation history of galaxies in a cosmological context. The CWD model unifies several starvation mechanisms knownExpand
A giant ring-like structure at 0.78
According to the cosmological principle, Universal large-scale structure is homogeneous and isotropic. The observable Universe, however, shows complex structures even on very large scales. The recentExpand
Ringing the initial Universe: the response of overdensity and transformed-density power spectra to initial spikes
We present an experiment in which we 'ring' a set of cosmological N-body-simulation initial conditions, placing spikes in the initial power spectrum at different wavenumber bins. We then measureExpand


How filaments of galaxies are woven into the cosmic web
LARGE-SCALE structure in the distribution of galaxies is thought to have evolved through gravitational instabilities from small density fluctuations in the (largely homogeneous) early Universe. ThisExpand
Crawling the cosmic network: exploring the morphology of structure in the galaxy distribution
Although coherent large-scale structures such as filaments and walls are apparent to the eye in galaxy redshift surveys, they have so far proven difficult to characterize with computer algorithms.Expand
Clusters, filaments, and voids in a universe dominated by cold dark matter
The behavior of a flat, cold dark matter universe is investigated on scales larger than 10 Mpc using a model in which galaxies are required to form only near high peaks of the smoothed linear densityExpand

Large scale structure of the universe and cosmological perturbation theory
Abstract We review the formalism and applications of non-linear perturbation theory (PT) to understanding the large-scale structure of the Universe. We first discuss the dynamics of gravitationalExpand
