The Accuracy of Subhalo Detection
Stuart I. Muldrew, Frazer R. Pearce, Chris Power
With the ever increasing resolution of N-body simulations, accurate subhalo detection is becoming essential in the study of the formation of structure, the production of merger tre…
Baryon fractions in clusters of galaxies: evidence against a preheating model for entropy generation
Owain E. Young, Peter A. Thomas, Chris J. Short +1
The Millennium Gas project aims to undertake smoothed-particle hydrodynamic resimulations of the Millennium Simulation, providing many hundred massive galaxy clusters for compariso…
The mass assembly of galaxy groups and the evolution of the magnitude gap
Ali A. Dariush, Somak Raychaudhury, Trevor J. Ponman +4
We investigate the assembly of groups and clusters of galaxies using the Millennium dark matter simulation and the associated gas simulations and semi-analytic catalogues of galaxi…
The evolution of galaxy cluster X-ray scaling relations
C. J. Short, P. A. Thomas, O. E. Young +3
We use numerical simulations to investigate, for the first time, the joint effect of feedback from supernovae (SNe) and active galactic nuclei (AGN) on the evolution of galaxy clus…
