The impact of mergers on relaxed X-ray clusters – I. Dynamical evolution and emergent transient structures
TL;DR: In this paper, a suite of smoothed particle hydrodynamics simulations of mergers involving idealized X-ray clusters whose initial conditions resemble relaxed clusters with cool compact cores observed by Chandra and XMM is presented.

Images, Structural Properties, and Metal Abundances of Galaxy Clusters Observed with Chandra ACIS-I at 0.1 < z < 1.3
TL;DR: This paper measured the mean metal abundance of the cluster gas as a function of redshift and found significant evolution, with the abundances dropping by 50% between z = 0.1 and z ≈ 1.5.

The evolution of large-scale structure in a universe dominated by cold dark matter
TL;DR: In this article, the results of numerical simulations of nonlinear gravitational clustering in universes dominated by weakly interacting, cold dark matter are presented and the evolution of the fundamental statistical properties of the models is described and their comparability with observation is discussed.

Cosmological Inflation and Large-Scale Structure
Andrew R. Liddle,David H. Lyth +1 more
TL;DR: This textbook is the first to provide a modern and unified overview of inflationary cosmology and carefully compares predictions with the latest observations, including those of the cosmic microwave background, the clustering and velocities of galaxies and the epoch of structure formation.

Merger rates in hierarchical models of galaxy formation
Cedric G. Lacey,Shaun Cole +1 more
TL;DR: In this article, an analytical description of the merging of virialized haloes is presented, which is applicable to any hierarchical model in which structure grows via gravitational instability, and the dependence of the merger rate on halo mass, epoch, the spectrum of initial density fluctuations and the density parameter Ω 0 is explicitly quantified.

Excursion set mass functions for hierarchical Gaussian fluctuations
TL;DR: In this paper, the authors proposed a solution based on the theory of the excursion sets of F(r, R sub f), the four-dimensional initial density perturbation field smoothed with a continuous hierarchy of filters of radii.

Concentrations of Dark Halos from Their Assembly Histories
TL;DR: In this article, the relation between the density profiles of dark matter halos and their mass assembly histories was studied using a statistical sample of halos in a high-resolution N-body simulation of the ΛCDM cosmology.
