    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 formation of giant elliptical galaxies and their globular cluster systems 
    West, Michael J.; Cote, Patrick; Marzke, Ronald O. (American Astronomical Society, 1998-07)
    We examine the formation of giant elliptical galaxies using their globular cluster (GC) systems as probes of their evolutionary history. The bimodal distributions of GC metallicities in such galaxies are often cited as ...

    Metal-poor lithium-rich giants in the radial velocity experiment survey 
    Ruchti, Gregory R.; Fulbright, Jon P.; Wyse, Rosemary F. G.; Gilmore, Gerard F.; Grebel, Eva K.; Bienayme, Olivier; Bland-Hawthorn, Joss; Freeman, Ken C.; Gibson, Brad K.; Munari, Ulisse (IOP Publishing Limited, 2011-12-20)
    We report the discovery of eight lithium-rich field giants found in a high-resolution spectroscopic sample of over 700 metal-poor stars ([Fe/H] < −0.5) selected from the Radial Velocity Experiment survey. The ...

    Modelling self-pollution of globular clusters from asymptotic giant branch stars 
    Fenner, Y.; Campbell, S.; Karakas, A. I.; Lattanzio, J. C.; Gibson, Brad K. (Royal Astronomical SocietyOxford University Press, 2004)
    A self-consistent model of the chemical evolution of the globular cluster NGC 6752 is presented to test a popular theory that observed abundance anomalies are due to ‘internal pollution’ from intermediate-mass asymptotic ...

    New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge 
    Majaess, Daniel J.; Borissova, J.; Chene, A.-N.; Ramirez Alegria, S.; Sharma, S.; Clarke, J. R. A.; Kurtev, R.; Negueruela, I.; Marco, A.; Amigo, P. (EDP Sciences, 2014)
    Context. VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Milky Way bulge and an adjacent ...
