What shapes the luminosity function of galaxies? (2003)
Journal Article
Benson, A., Bower, R., Frenk, C., Lacey, C., Baugh, C., & Cole, S. (2003). What shapes the luminosity function of galaxies?. Astrophysical Journal, 599(1), 38-49. https://doi.org/10.1086/379160

We investigate the physical mechanisms that shape the luminosity function of galaxies in hierarchical clustering models. Beginning with the mass function of dark matter halos in the CDM ( cold dark matter) cosmology, we show, in incremental steps, ho... Read More about What shapes the luminosity function of galaxies?.

Journal Article
Hawkins, E., Maddox, S., Cole, S., Lahav, O., Madgwick, D., Norberg, P., …Taylor, K. (2003). The 2dF Galaxy Redshift Survey: correlation functions, peculiar velocities and the matter density of the Universe. Monthly Notices of the Royal Astronomical Society, 346(1), 78-96. https://doi.org/10.1046/j.1365-2966.2003.07063.x

We present a detailed analysis of the two-point correlation function, ξ(σ, π), from the 2dF Galaxy Redshift Survey (2dFGRS). The large size of the catalogue, which contains ∼220 000 redshifts, allows us to make high-precision measurements of various...

The 2dF Galaxy Redshift Survey: galaxy clustering per spectral type (2003)
Journal Article

We have calculated the two-point correlation functions in redshift space, ξ(σ, π), for galaxies of different spectral types in the 2dF Galaxy Redshift Survey. Using these correlation functions, we are able to estimate values of the linear redshift-sp... Read More about The 2dF Galaxy Redshift Survey: galaxy clustering per spectral type.

The halo occupation distribution and the physics of galaxy formation (2003)
Journal Article
Berlind, A., Weinberg, D., Benson, A., Baugh, C., Cole, S., Davé, R., …Lacey, C. (2003). The halo occupation distribution and the physics of galaxy formation. Astrophysical Journal, 593(1), 1-25. https://doi.org/10.1086/376517

The halo occupation distribution (HOD) describes the bias between galaxies and dark matter by specifying (1) the probability P(N|M) that a halo of virial mass M contains N galaxies of a particular class and (2) the relative spatial and velocity distr...

The properties of spiral galaxies : confronting hierarchical galaxy formation models with observations (2003)
Journal Article

We compare the properties of local spiral galaxies with the predictions of the Cole et al. semi-analytic model of hierarchical galaxy formation, in order to gain insight into the baryonic processes, such as gas cooling and star formation, that were r...

The effects of photoionization on galaxy formation - III. Environmental dependence in the luminosity function (2003)
Journal Article
Benson, A., Frenk, C., Baugh, C., Cole, S., & Lacey, C. (2003). The effects of photoionization on galaxy formation - III. Environmental dependence in the luminosity function. Monthly Notices of the Royal Astronomical Society, 343(2), 679-691. https://doi.org/10.1046/j.1365-8711.2003.06709.x

Using semi-analytic modelling techniques, we calculate the luminosity function of galaxy populations residing in cold dark matter haloes of different masses. We pay particular attention to the influence of the re-ionization of the Universe on the num... Read More about The effects of photoionization on galaxy formation - III.

The 2dF Galaxy Redshift Survey: the luminosity function of cluster galaxies. (2003)
Journal Article

We have determined the composite luminosity function (LF) for galaxies in 60 clusters from the 2dF Galaxy Redshift Survey. The LF spans the range −22.5 < Mmath image < −15, and is well fitted by a Schechter function with M*math image=−20.07 ± 0.07 an...

Galaxy formation using halo merger histories taken from N-body simulations (2003)
Journal Article

We develop a hybrid galaxy formation model that uses outputs from an N-body simulation to follow the merger histories (or ‘merger trees’) of dark matter haloes and treats baryonic processes, such as the cooling of gas within haloes and subsequent sta...

We compare the results of two techniques used to calculate the evolution of cooling gas during galaxy formation: smooth particle hydrodynamics (SPH) simulations and semi-analytic modelling. We improve upon the earlier statistical comparison of Benson... Read More about A comparison of gas dynamics in smooth particle hydrodynamics and semi-analytic models of galaxy formation.
