The origin of discs and spheroids in simulated galaxies
- Physics
- 2011
The major morphological features of a galaxy are thought to be determined by the assembly history and net spin of its surrounding dark halo. In the simplest scenario, disc galaxies form predominantly…
Simulations of Galaxy Formation in a ΛCDM Universe. III. The Dissipative Formation of an Elliptical Galaxy
- Physics
- 2003
We examine the dynamical structure of an elliptical galaxy simulated in the ΛCDM scenario. The morphology of the galaxy evolves dramatically over time in response to the mode and timing of mass…
The Secular Evolution of Disk Structural Parameters
- Physics
- 2006
We present a comprehensive series of simulations to study the secular evolution of disk galaxies expected in a ΛCDM universe. Our simulations are organized in a hierarchy of increasing complexity,…
The formation of a disk galaxy within a growing dark halo
- Physics
- 2003
We present a dynamical model for the formation and evolution of a massive disk galaxy, within a growing dark halo whose mass evolves according to cosmological simulations of structure formation. The…

We simulate the formation and chemodynamical evolution of 128 elliptical galaxies using a GRAPE-SPH code that includes various physical processes that are associated with the formation of stellar…
Stars beyond galaxies: the origin of extended luminous haloes around galaxies
- Physics

We use numerical simulations to investigate the origin and structure of the luminous haloes that surround isolated galaxies. These stellar structures extend out to several hundred kpc away from a…
On the continuous formation of field spheroidal galaxies in hierarchical models of structure formation
- Physics
- 2002
We re-examine the assembly history of field spheroidals as a potentially powerful discriminant of galaxy formation scenarios. Whereas monolithic collapse and hierarchical, merger-driven, models…

We simulate the formation and chemodynamical evolution of 124 elliptical galaxies using a GRAPE-SPH code that includes various physical processes that are associated with the formation of stellar…
Bars, Ovals, and Lenses in Early-Type Disk Galaxies: Probes of Galaxy Evolution
- Physics
- 2009
The origin of S0 galaxies is discussed in the framework of early mergers in a cold dark matter cosmology, and in a scenario where S0s are assumed to be former spirals stripped of gas. From an…

We use a semianalytic model of galaxy formation in hierarchical clustering theories to interpret recent data on galaxy formation and evolution, focusing primarily on the recently discovered…
The Cosmological Origin of the Tully-Fisher Relation
- Physics

We use high-resolution cosmological simulations that include the effects of gasdynamics and star formation to investigate the origin of the Tully-Fisher relation in the standard cold dark matter…
Origin of kinematic subsystems in elliptical galaxies
- PhysicsNature
- 1991
ELLIPTICAL galaxies were once thought to be smooth, featureless stellar systems with little or no substructure, but increasingly sophisticated observations are challenging this point of view. Some…
The nature of high-redshift galaxies
- Physics
- 1998
Abstract Using semi-analytic models of galaxy formation, we investigate the properties of z∼3 galaxies and compare them with the observed population of Lyman-break galaxies (LBGs). In addition to the…
The formation and evolution of galaxies within merging dark matter haloes

We present self-consistent 3D simulations of the formation of virialized systems containing both gas and dark matter. Using a fully Lagrangian code based on the smooth particle hydrodynamics…
The evolution of barred spiral galaxies in the Hubble Deep Fields North and South
- Physics

Using deep near-infrared and optical observations of the Hubble Deep Field-North from the Hubble Space Telescope NICMOS and WFPC2 instruments and from the ground, we examine the spectral energy…
Debris streams in the solar neighbourhood as relicts from the formation of the Milky Way
- PhysicsNature
- 1999
It is now generally believed that galaxies were built up through gravitational amplification of primordial fluctuations and the subsequent merging of smaller precursor structures. The stars of the…
