Cosmic structure has formed as a result of gravitational amplification of primordial density fluctuations together with the action of other physical processes (adiabatic gas dynamics, radiative cooling, photoionization and recombination, radiative transfer). These complex nonlinear processes, acting over a wide range of length scales (from kiloparsecs to tens of megaparsecs), make this a difficult problem for computation. During the last two decades, significant progress has been made in…

Physical Models of Galaxy Formation in a Cosmological Framework
Modeling galaxy formation in a cosmological context presents one of the greatest challenges in astrophysics today due to the vast range of scales and numerous physical processes involved. Here we
Simulations of structure formation in the universe: hot vs. cold dark matter
In the last century, new observational techniques and discoveries such as the Cosmic Microwave Background Radiation have brought a new dimension of knowledge about the Universe. Therefore new

The thorny problem of how galaxies trace the overall mass on large scales may be yielding some ground, but efforts to resolve smaller–scale features of galaxies are challenged by the complex nature of star–gas interactions on kiloparsec scales.
Robustness of Cosmological Simulations. I. Large-Scale Structure
The gravitationally driven evolution of cold dark matter dominates the formation of structure in the universe over a wide range of length scales. While the longest scales can be treated by
Computational Cosmology: from the Early Universe to the Large Scale Structure
A sample of numerical calculations addressing specific issues in cosmology are reviewed, from the Big Bang singularity dynamics to the fundamental interactions of gravitational waves; from the quark-hadron phase transition to the large scale structure of the Universe.
Formation of the First Supermassive Black Holes in the Early Universe
To explain the formation of the first supermassive black holes in the universe, we present a scenario based on direct collapse of baryonic gas in massive halos at high redshift. We test this scenario
Computational Cosmology: From the Early Universe to the Large Scale Structure
A sample of numerical calculations (and numerical methods applied to specific issues in cosmology) from the Big Bang singularity dynamics to the fundamental interactions of gravitational waves; from the quark-hadron phase transition to the large scale structure of the Universe.
Formation of Galaxy Clusters
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
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


Analysis of galaxy formation with hydrodynamics
We present a hydrodynamical code based on the Smooth Particle Hydrodynamics technique implemented in an AP3M code aimed at solving the hydrodynamical and gravitational equations in a cosmological
Dissipational galaxy formation. II - Effects of star formation
Numerical simulations of hierarchical galaxy formation, including gasdynamics, star formation, and supernova feedback, are presented. The simulations model the collapse of isolated constant-density
Hierarchical galaxy formation : overmerging and the formation of an X-ray cluster
We simulate the formation of a moderately rich cluster in a cold dark matter universe using a technique which allows us to follow both the dark matter and the baryonic gas. Gas is able to shock-heat,
Simulations of dissipative galaxy formation in hierarchically clustering universes – I: Tests of the code
We present tests of a code designed to simulate the evolution of self-gravitating fluids in three dimensions. The code is based on the smoothed-particle hydrodynamics (SPH) technique for solving the

Numerical simulations of hierarchical galaxy formation including gasdynamics are presented. These simulations are conducted using a new, general-purpose programs for evolving self-gravitating systems
Cold Dark Matter Cosmology with Hydrodynamics and Galaxy Formation: The Evolution of the Intergalactic Medium and Background Radiation Fields
We have supplemented our code, which computes the evolution of the physical state of a representative piece of the universe to include, not only the dynamics of dark matter (with a standard PM code),

The thermodynamic history of the hot intracluster medium in a cluster of Coma richness was examined using a numerical simulation incorporating three-dimensional hydrodynamics of a collisional
Two-Fluid Simulations of Galaxy Formation
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

N-body models used to study the formation of structure in Ω = 1 universes reveal that the mass profiles of the collapsed structures—galactic haloes—are intimately related to the power spectrum of
The evolution of large-scale structure in a universe dominated by cold dark matter
The results of numerical simulations of nonlinear gravitational clustering in universes dominated by weakly interacting, 'cold' dark matter are presented. The numerical methods used and the way in
