Research

Together with my supervisor, Ian McCarthy, I am investigating a number of fundamental questions related to galaxy groups and clusters from a theoretical perspective. How accurate are weak lensing measurements of cluster masses and concentrations? What is the effect of the ICM on galaxies? Why are galaxies in the far outskirts of groups and clusters different from those in the field? These questions are addressed through detailed analyses of large cosmological simulations. At the moment, most of this work uses the hydrodynamic GIMIC simulation suite, but I have also worked on the Dark Matter only Millennium Simulation before.
