  • Evidence for an accretion origin for the outer halo globular cluster system of M31 

    Mackey, Dougal, Avon Huxor, Annette Ferguson, Mike Irwin, et al. 2010. "Evidence for an accretion origin for the outer halo globular cluster system of M31." The Astrophysical Journal Letters 717(1): L11.
    We use a sample of newly-discovered globular clusters from the Pan-Andromeda Archaeological Survey (PAndAS) in combination with previously-catalogued objects to map the spatial distribution of globular clusters in the M31 ...

  • A Keck/DEIMOS Kinematic Study of Andromeda IX: dark matter on the smallest galactic scales 

    Chapman, Scott C., Rodrigo Ibata, Geraint F. Lewis, Annette M. N. Ferguson, et al. 2005. "A Keck/DEIMOS Kinematic Study of Andromeda IX: dark matter on the smallest galactic scales." The Astrophysical Journal 632(2): 87-L90
    We present the results of a kinematic survey of the dwarf spheroidal satellite of M31, And-IX, which appears to be the lowest surface brightness and also the faintest galaxy (M_V = -8.3) found to date. Using Keck/DEIMOS ...

  • A trio of new Local Group galaxies with extreme properties 

    McConnachie, Alan, Avon Huxor, Nicolas Martin, Mike Irwin, et al. 2008. "A trio of new Local Group galaxies with extreme properties." The Astrophysical Journal 688(2): 1009-1020
    We report on the discovery of three new dwarf galaxies in the Local Group. These galaxies are found in new CFHT/MegaPrime g,i imaging of the south-western quadrant of M31, extending our extant survey area to include the ...
