Testing the predictions of the cold dark matter model for the sizes, colours, morphologies and luminosities of galaxies with the SDSS
J. E. Gonzalez, C. G. Lacey, C. M. Baugh +2
The huge size and uniformity of the Sloan Digital Sky Survey makes possible an exacting test of current models of galaxy formation. We compare the predictions of the GALFORM semi-a…
Extremely Red Objects in a hierarchical universe
V. Gonzalez-Perez, C. M. Baugh, C. G. Lacey +1
We analyse whether hierarchical formation models based on Lambda cold dark matter cosmology can produce enough massive red galaxies to match observations. For this purpose, we comp…
Massive, red galaxies in a hierarchical universe I. Counts of Extremely Red Objects and basic properties
V. Gonzalez-Perez, C. M. Baugh, C. G. Lacey +1
We present predictions for the abundance and nature of Extremely Red Objects (EROs) in the Lambda cold dark matter model. EROs are red, massive galaxies observed at z>= 1 and their…
The Fate of Substructures in Cold Dark Matter Haloes
R. E. Angulo, C. G. Lacey, C. M. Baugh +1
We use the Millennium Simulation, a large, high resolution N-body simulation of the evolution of structure in a LambdaCDM cosmology, to study the properties and fate of substructur…
The Properties of Sub-mm Galaxies in Hierarchical Models
Mark Swinbank, Cedric Lacey, Ian Smail +8
We use the combined GALFORM semi-analytical model of galaxy formation and GRASIL spectrophotometric code to investigate the properties of galaxies selected via their sub-mm emissio…
The clustering of Ly-alpha emitters in a LambdaCDM Universe
A. Orsi, C. G. Lacey, C. M. Baugh +1
We combine a semi-analytical model of galaxy formation with a very large simulation which follows the growth of large scale structure in a LambdaCDM universe to predict the cluster…
The Colours of Satellite Galaxies in Groups and Clusters
Andreea S. Font, Richard G. Bower, Ian G. McCarthy +6
Current models of galaxy formation predict satellite galaxies in groups and clusters that are redder than observed. We investigate the effect on the colours of satellite galaxies p…
