    Advanced morphological galaxy classification: a comparison of observed and simulated galaxies 
    Hambleton, K. M.; Gibson, Brad K.; Brook, C. B.; Stinson, G. S.; Conselice, C. J.; Bailin, J.; Couchman, H.; Wadsley, J. (Royal Astronomical SocietyOxford University Press, 2011)
    Encoded within the morphological structure of galaxies are clues related to their formation and evolutionary history. Recent advances pertaining to the statistics of galaxy morphology include sophisticated measures of ...

    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 ...

    Hierarchical formation of bulgeless galaxies – II. Redistribution of angular momentum via galactic fountains 
    Gibson, Brad K.; Brook, C. B.; Stinson, G.; Roskar, R.; Wadsley, J.; Quinn, T. (Oxford University Press, 2012-01)
    Within a fully cosmological hydrodynamical simulation, we form a galaxy which rotates at 140 km s[superscript −1], and it is characterized by two loose spiral arms and a bar, indicative of a Hubble-type SBc/d galaxy. We ...

    MaGICC baryon cycle: the enrichment history of simulated disc galaxies 
    Brook, C. B.; Stinson, G.; Gibson, Brad K.; Shen, S.; Maccio, A. V.; Obreja, A.; Wadsley, J.; Quinn, T. (Oxford University Press, 2014-10-01)
    Using cosmological galaxy formation simulations from the MaGICC (Making Galaxies in a Cosmological Context) project, spanning stellar mass from ∼107 to 3 × 1010 M☉, we trace the ...

    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 ...

    Thin disc, thick disc and halo in a simulated galaxy 
    Gibson, Brad K.; Brook, C. B.; Stinson, G. S.; Kawata, D.; House, E. L.; Miranda, M. S.; Maccio, A. V.; Pilkington, K.; Roskar, R.; Wadsley, J. (Royal Astronomical Society, 2012-10)
    Within a cosmological hydrodynamical simulation, we form a disc galaxy with subcomponents which can be assigned to a thin stellar disc, thick disc and a low-mass stellar halo via a chemical decomposition. The thin- and ...
