    The distribution of metals in cosmological hydrodynamical simulations of dwarf disc galaxies 
    Pilkington, K.; Gibson, Brad K.; Brook, C. B.; Calura, F.; Stinson, G. S.; Thacker, Robert John, 1970-; Michel-Dansac, L.; Bailin, J.; Couchman, H. M. P.; Wadsley, J. (Oxford University Press, 2012-09)
    We examine the chemical properties of five cosmological hydrodynamical simulations of an M33-like disc galaxy which have been shown previously to be consistent with the morphological characteristics and bulk scaling relations ...

    Halo expansion in cosmological hydro simulations: toward a baryonic solution of the cusp/core problem in massive spirals 
    Gibson, Brad K.; Maccio, A. V.; Stinson, G.; Brook, C. B.; Wadsley, J.; Couchman, H. M. P.; Shen, S.; Quinn, T. (American Astronomical SocietyIOP Publishing, 2012-01-01)
    A clear prediction of the cold dark matter (CDM) model is the existence of cuspy dark matter halo density profiles on all mass scales. This is not in agreement with the observed rotation curves of spiral galaxies, challenging ...

    MAGICC haloes: confronting simulations with observations of the circumgalactic medium at z = 0 
    Stinson, G. S.; Brook, C.; Prochaska, J. Xavier; Hennawi, Joe; Shen, Sijing; Wadsley, J.; Pontzen, Andrew; Couchman, H. M. P.; Quinn, T.; Maccio, Andrea V.; Gibson, Brad K. (Wiley-Blackwell, 2012-09)
    We explore the circumgalactic medium (CGM) of two simulated star-forming galaxies with luminosities L ≈ 0.1 and 1 L★ generated using the smooth particle hydrodynamic code GASOLINE. These simulations are ...

    On the estimation and detection of the Rees–Sciama effect 
    Fullana, M. J.; Arnau, J. V.; Thacker, Robert John, 1970-; Couchman, H. M. P.; Sáez, D. (Oxford University Press, 2017-02)
    Maps of the Rees–Sciama (RS) effect are simulated using the parallel N-body code, hydra, and a run-time ray-tracing procedure. A method designed for the analysis of small, square cosmic microwave background (CMB) maps is ...
