Formation of galaxy clusters corresponds to the collapse of the largest gravitationally bound overdensities in the initial density field and is accompanied by the most energetic phenomena since the Big Bang and by the complex interplay between gravity-induced dynamics of collapse and baryonic processes associated with galaxy formation. Galaxy clusters are, thus, at the cross-roads of cosmology and astrophysics and are unique laboratories for testing models of gravitational structure formation… 
A Baryonic Effect on the Merger Timescale of Galaxy Clusters
Accurate estimation of the merger timescale of galaxy clusters is important to understand the cluster merger process and further the formation and evolution of the large-scale structure of the
Large-Scale Structure Formation: From the First Non-linear Objects to Massive Galaxy Clusters
The large-scale structure of the Universe formed from initially small perturbations in the cosmic density field, leading to galaxy clusters with up to 1015 M⊙ at the present day. Here, we review the
Structures and Components in Galaxy Clusters: Observations and Models
Clusters of galaxies are the largest gravitationally bounded structures in the Universe dominated by dark matter. We review the observational appearance and physical models of plasma structures in
Cosmic Rays in Galaxy Clusters and Their Interaction with Magnetic Fields
Cosmic rays can be accelerated in galaxy clusters by different mechanisms and remain confined in the cluster volume accumulating for cosmological times. This component is expected to generate
The Role of Baryons and Neutrinos in the Evolution of Large-Scale Structure
Galaxy groups and clusters (GGCs) hold a privileged position within the cosmological hierarchy. As the most recent structures to have formed, their abundances, spatial distribution and individual
Clusters of galaxies
Galaxy clusters are formed via nonlinear growth of primordial density fluctuations and are the most massive gravitationally bound objects in the present Universe. Their number density at different
Towards a realistic population of simulated galaxy groups and clusters
We present a new suite of large-volume cosmological hydrodynamical simulations called cosmo-OWLS. They form an extension to the OverWhelmingly Large Simulations (OWLS) project, and have been designed
A model for intergalactic filaments and galaxy formation during the first gigayear
We propose a physically based, analytic model for intergalactic filaments during the first gigayear of the universe. The structure of a filament is based upon a gravitationally bound, isothermal
The history of chemical enrichment in the intracluster medium from cosmological simulations
The distribution of metals in the intracluster medium (ICM) of galaxy clusters provides valuable information on their formation and evolution, on the connection with the cosmic star formation and on
Constraining f(R) gravity with Planck data on galaxy cluster profiles
Models of $f(R)$ gravity that introduce corrections to the Newtonian potential in the weak field limit are tested at the scale of galaxy clusters. These models can explain the dynamics of spiral and

Cosmological Simulations of Galaxy Clusters
We review recent progress in the description of the formation and evolution of galaxy clusters in a cosmological context by using state-of-art numerical simulations. We focus our presentation on the
The flip side of galaxy formation: a combined model of galaxy formation and cluster heating
Only ~10 per cent of baryons in the Universe are in the form of stars, yet most models of luminous structure formation have concentrated on the properties of the luminous stellar matter. Such models
Galaxy formation by gravitational collapse
Galaxies may form by the collapse of density perturbations in a universe dominated by dark matter. In this scenario, the growth of density and velocity distributions around collapsed mass peaks is
The formation and evolution of clusters of galaxies in different cosmogonies
The formation of galaxy clusters in hierarchically clustering universes is investigated by means of high-resolution N-body simulations. The simulations are performed using a newly developed multimass
Simulations of cosmic-ray feedback by active galactic nuclei in galaxy clusters
Feedback processes by active galactic nuclei (AGN) appear to be a key for understanding the nature of the very X-ray luminous cool cores found in many clusters of galaxies. We investigate a numerical

We study the merging history of dark matter haloes that end up in rich clusters, using N-body simulations of a scale-free universe. We compare the predictions of the extended Press &38; Schechter
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. This

We investigate the formation of galaxies and larger structure with a simulation modeling two gravitationally coupled fluids representing dark matter and baryons. The baryon gas dynamics are
Evolution of Clusters of Galaxies
In hierarchical models for structure formation like CDM, the mass scale of clustering evolves rapidly and clusters in the past are predicted to be less massive, but denser and more numerous. The
