    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 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 ...

    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 ...
