The baryon fraction of LambdaCDM haloes
Robert A. Crain, Vincent R. Eke, Carlos S. Frenk +4
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…
The spin and shape of dark matter haloes in the Millennium simulation of a LambdaCDM universe
Philip Bett, Vincent Eke, Carlos S. Frenk +3
We investigate the spins and shapes of over a million dark matter haloes identified at z=0 in the Millennium simulation. Our sample spans halo masses ranging from dwarf galaxies to…
Galaxy Groups in the 2dFGRS: the number density of groups
V. R. Eke, C. M. Baugh, S. Cole +2
The abundance of galaxy clusters as a function of mass is determined using the 2dFGRS Percolation-Inferred Galaxy Group (2PIGG) catalogue. This is used to estimate the amplitude of…
The effects of feedback on the morphology of galaxy discs
Takashi Okamoto, Vince R. Eke, Carlos S. Frenk +1
We have performed hydrodynamic simulations of galaxy formation in a LCDM universe. We have followed galaxy formation in a dark matter halo, chosen to have a relatively quiet recent…
The 2dF Galaxy Redshift Survey: Power-spectrum analysis of the final dataset and cosmological implications
S. Cole, W. J. Percival, J. A. Peacock +28
We present a power spectrum analysis of the final 2dF Galaxy Redshift Survey, employing a direct Fourier method. The sample used comprises 221,414 galaxies with measured redshifts.…
Momentum transfer across shear flows in Smoothed Particle Hydrodynamic simulations of galaxy formation
T. Okamoto, A. Jenkins, V. R. Eke +2
We investigate the evolution of angular momentum in SPH simulations of galaxy formation, paying particular attention to artificial numerical effects. We find that a cold gas disc f…
