Clustering of galaxies in a hierarchical universe - I. Methods and results at z=0
- G. Kauffmann, J. Colberg, A. White
- Physics
- 21 May 1998
We introduce a new technique for following the formation and evolution of galaxies in cosmological N-body simulations. Dissipationless simulations are used to track the formation and merging of dark…

Direct Cosmological Simulations of the Growth of Black Holes and Galaxies
- T. D. Matteo, J. Colberg, V. Springel, L. Hernquist, D. Sijacki
- Physics
- 16 May 2007
We investigate the coupled formation and evolution of galaxies and their embedded supermassive black holes using state-of-the-art hydrodynamic simulations of cosmological structure formation. For the…
Clustering of galaxies in a hierarchical universe — II. Evolution to high redshift
- G. Kauffmann, J. Colberg, A. Diaferio, S. White
- Physics
- 14 September 1998
In hierarchical cosmologies the evolution of galaxy clustering depends both on cosmological quantities such as Ω, Λ and P(k), which determine how collapsed structures – dark matter haloes – form and…
Voids in a ΛCDM universe
- J. Colberg, R. Sheth, A. Diaferio, Liang Gao, N. Yoshida
- Physics
- 7 September 2004
We study the formation and evolution of voids in the dark matter distribution using various simulations of the popular A cold dark matter cosmogony. We identify voids by requiring them to be regions…
The Aspen-Amsterdam void finder comparison project
- J. Colberg, F. Pearce, D. University
- Physics
- 6 March 2008
Despite a history that dates back at least a quarter of a century studies of voids in the large–scale structure of the Universe are bedevilled by a major problem: there exist a large number of quite…
Intercluster filaments in a ΛCDM Universe
- J. Colberg, K. Krughoff, A. Connolly
- Physics
- 29 June 2004
The large-scale structure (LSS) in the Universe comprises a complicated filamentary network of matter. We study this network using a high-resolution simulation of structure formation in a A Cold Dark…
Clustering of galaxies in a hierarchical universe — III. Mock redshift surveys
- A. Diaferio, G. Kauffmann, J. Colberg, S. White
- Physics
- 1 December 1998
This is the third paper in a series which combines N-body simulations and semi-analytic modelling to provide a fully spatially resolved simulation of the galaxy formation and clustering processes.…
Quantifying cosmic superstructures
- J. Colberg
- Physics
- 20 November 2006
The large-scale structure (LSS) found in galaxy redshift surveys and in computer simulations of cosmic structure formation shows a very complex network of galaxy clusters, filaments and sheets around…
Linking cluster formation to large-scale structure
- J. Colberg, S. White, A. Jenkins, F. Pearce
- Physics
- 5 November 1997
ABSTRA C T We use two high-resolution cold dark matter (CDM) simulations to investigate how the formation of clusters of galaxies is related to the distribution of the surrounding mass. It is well…
