Testing Cold Dark Matter with the hierarchical buildup of stellar light (2008)
Balogh, Michael L., McCarthy, Ian G., Bower, Richard G., Eke, Vincent R.
(Abridged) We demonstrate that the tenet of hierarchical structure growth leads directly to a robust, falsifiable prediction for the correlation between stellar fraction (fstar) and total system mass...
The baryon fraction of LambdaCDM haloes (2006)
Crain, Robert A., Eke, Vincent R., Frenk, Carlos S., Jenkins, Adrian, McCarthy, Ian G., Navarro, Julio F., ...
We investigate the baryon fraction in dark matter haloes formed in non-radiative gas-dynamical simulations of the LambdaCDM cosmogony. By combining a realisation of the Millennium Simulation...
Cole, Shaun, Percival, Will, Peacock, John A., Norberg, Peder, Baugh, Carlton, Frenk, Carlos S., ...
We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing a direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts. We...

The 2dF Galaxy Redshift Survey: the clustering of galaxy groups (2004)
Padilla, Nelson D., Baugh, Carlton M., Eke, Vincent R., Norberg, Peder, Cole, Shaun, Frenk, Carlos S., ...
On the nature of the ring-like structure in the outer Galactic disk (2003)
Helmi, Amina, Navarro, Julio F., Meza, Andres, Steinmetz, Matthias, Eke, Vincent R.
We examine the tidal disruption of satellite galaxies in a cosmological simulation of the formation of a disk galaxy in the $\Lambda$CDM scenario. We find that the disruption of satellite galaxies in...
Meza, Andres, Navarro, Julio F., Steinmetz, Matthias, Eke, Vincent R.
We examine in detail the dynamical structure of an elliptical galaxy simulated in the Lambda CDM scenario. The morphology of the galaxy evolves dramatically over time in response to the mode and...
Abadi, Mario G., Navarro, Julio F., Steinmetz, Matthias, Eke, Vincent R.
We present a detailed analysis of the dynamical properties of a simulated disk galaxy assembled hierarchically in the Lambda CDM cosmogony. At z=0, two distinct dynamical components are identified on...
Abadi, Mario G., Navarro, Julio F., Steinmetz, Matthias, Eke, Vincent R.
We analyze the properties of a disk galaxy simulated with unprecedented numerical resolution in the Lambda CDM cosmogony. The galaxy is assembled through a number of high-redshift mergers followed by...
Measuring Sigma8 with Cluster Lensing : Biases from Unrelaxed Clusters (2002)
Smith, Graham P., Edge, Alastair C., Eke, Vincent R., Nichol, Robert C., Smail, Ian, Kneib, Jean-Paul
We use gravitational lens models and X-ray spectral analysis of ten X-ray luminous galaxy clusters at z~0.2 to study the impact of cluster substructure on attempts to normalize the matter power...
Kneissl, Ruediger, Jones, Michael E., Saunders, Richard, Eke, Vincent R., Lasenby, Anthony N., Grainge, Keith, ...
We discuss prospects for cluster detection via the Sunyaev-Zel'dovich (SZ) effect in a blank field survey with the proposed interferometer array, the Arcminute MicroKelvin Imager (AMI). Clusters of...
The Evolution of X-ray Clusters in Low Density Universes (1997)
Eke, Vincent R., Navarro, Julio F., Frenk, Carlos S.
We present results of N-body/gasdynamical simulations designed to investigate the evolution of X-ray clusters in a flat, low-density, cold dark matter (CDM) cosmogony. The density profile of the dark...
The Cores of Dwarf Galaxy Halos (1996)
Navarro, Julio F., Eke, Vincent R., Frenk, Carlos S.
We use N-body simulations to examine the effects of mass outflows on the density profiles of cold dark matter (CDM) halos surrounding dwarf galaxies. In particular, we investigate the consequences of...
Cluster correlation functions in N-body simulations (1996)
Eke, Vincent R., Cole, Shaun, Frenk, Carlos S., Navarro, Julio F.
The correlation function of galaxy clusters has often been used as a test of cosmological models. A number of assumptions are implicit in the comparison of theoretical expectations to data. Here we...
Using the Evolution of Clusters to Constrain Omega (1996)
Eke, Vincent R., Cole, Shaun, Frenk, Carlos S.
The population of rich galaxy clusters evolves much more rapidly in a universe with critical density than one with low density, thus offering the possibility of determining the cosmological density...
