    The properties of the local spiral arms from RAVE data: two-dimensional density wave approach 
    Siebert, A.; Famaey, B.; Binney, J.; Burnett, B.; Faure, C.; Minchev, I.; Williams, M. E. K.; Bienayme, O.; Bland-Hawthorn, J.; Boeche, C.; Gibson, Brad K. (Oxford University Press, 2012-09)
    Using the Radial Velocity Experiment (RAVE) survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likely originates from ...

    RAMSES-CH: a new chemodynamical code for cosmological simulations 
    Gibson, Brad K.; Few, C. G.; Courty, S.; Kawata, D.; Calura, F.; Teyssier, R. (Oxford University Press on behalf of the Royal Astronomical Society, 2012-07)
    We present a new chemodynamical code – RAMSES-CH – for use in simulating the self-consistent evolution of chemical and hydrodynamical properties of galaxies within a fully cosmological framework. We build upon the adaptive ...

    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 ...

    The VMC survey – V. First results for classical Cepheids 
    Ripepi, V.; Moretti, M. I.; Marconi, M.; Clementini, G.; Cioni, M.-R. L.; Marquette, J. B.; Girardi, L.; Rubele, S.; Groenewegen, M. A. T.; de Grijs, R.; Gibson, Brad K. (Oxford University Press, 2012-08)
    The VISTA Magellanic Cloud (VMC; PI: M.-R. L. Cioni) survey is collecting deep Ks-band time series photometry of the pulsating variable stars hosted by the system formed by the two Magellanic Clouds (MCs) and ...
