    The chemical evolution of globular clusters – II. Metals and fluorine 
    Sanchez-Blazquez, P.; Marcolini, A.; Gibson, Brad K.; Karakas, A. I.; Pilkington, K.; Calura, F. (Oxford University Press, 2012-01)
    In the first paper of this series, we proposed a new framework in which to model the chemical evolution of globular clusters. This model is predicated upon the assumption that clusters form within an interstellar medium ...

    The cold gas content of bulgeless dwarf galaxies 
    Pilkington, K.; Gibson, Brad K.; Calura, F.; Brooks, A. M.; Mayer, L.; Brook, C. B.; Stinson, G. S.; Thacker, Robert John, 1970-; Few, C. G.; Cunnama, D. (Wiley-Blackwell, 2011-11)
    We present an analysis of the neutral hydrogen (H I) properties of a fully cosmological hydrodynamical dwarf galaxy, run with varying simulation parameters. As reported by Governato et al., the high-resolution, high star ...

    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 ...

    Metallicity gradients in disks: Do galaxies form inside-out? 
    Pilkington, K.; Few, C. G.; Gibson, Brad K.; Calura, F.; Michel-Dansac, L.; Thacker, Robert John, 1970-; Molla, M.; Matteucci, F.; Rahimi, A.; Kawata, D. (EDP Sciences, 2012-04)
    Aims. We examine radial and vertical metallicity gradients using a suite of disk galaxy hydrodynamical simulations, supplemented with two classic chemical evolution approaches. We determine the rate of change of gradient ...

    The role of feedback in shaping the structure of the interstellar medium 
    Walker, A. P.; Gibson, Brad K.; Pilkington, K.; Brook, C. B.; Dutta, P.; Stanimirovic, S.; Stinson, G. S.; Bailin, J. (Oxford University Press, 2014-06)
    We present an analysis of the role of feedback in shaping the neutral hydrogen (H I) content of simulated disc galaxies. For our analysis, we have used two realizations of two separate Milky Way-like (∼L★) discs – ...

    The stellar metallicity distribution of disc galaxies and bulges in cosmological simulations 
    Gibson, Brad K.; Calura, F.; Michel-Dansac, L.; Stinson, G. S.; Dotter, A.; Pilkington, K.; House, E. L.; Brook, C. B.; Few, C. G.; Cignoni, M. (Royal Astronomical Society, 2012-12)
    By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a ...

    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 ...
