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?.

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...

On the origin of intracluster entropy (2003)
Journal Article
Voit, G., Balogh, M., Bower, R., Lacey, C., & Bryan, G. (2003). On the origin of intracluster entropy. Astrophysical Journal, 593(1), 272-290. https://doi.org/10.1086/376499

The entropy distribution of the intracluster medium and the shape of its confining potential well completely determine the X-ray properties of a relaxed cluster of galaxies, motivating us to explore the origin of intracluster entropy and to describe...

The properties of spiral galaxies : confronting hierarchical galaxy formation models with observations (2003)
Journal Article
Bell, E., Baugh, C., Cole, S., Frenk, C., & Lacey, C. (2003). The properties of spiral galaxies : confronting hierarchical galaxy formation models with observations. Monthly Notices of the Royal Astronomical Society, 343(2), 367-384. https://doi.org/10.1046/j.1365-8711.2003.06673.x

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. Environmental dependence in the luminosity function.

Galaxy formation using halo merger histories taken from N-body simulations (2003)
Journal Article
Helly, J., Cole, S., Frenk, C., Baugh, C., Benson, A., & Lacey, C. (2003). Galaxy formation using halo merger histories taken from N-body simulations. Monthly Notices of the Royal Astronomical Society, 338(4), 903-912. https://doi.org/10.1046/j.1365-8711.2003.06151.x

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...

A comparison of gas dynamics in smooth particle hydrodynamics and semi-analytic models of galaxy formation (2003)
Journal Article
Helly, J., Cole, S., Frenk, C., Baugh, C., Benson, A., Lacey, C., & Pearce, F. (2003). A comparison of gas dynamics in smooth particle hydrodynamics and semi-analytic models of galaxy formation. Monthly Notices of the Royal Astronomical Society, 338(4), 913-925. https://doi.org/10.1046/j.1365-8711.2003.06152.x

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.
