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

    Mackey, Dougal; Huxor, Avon; Ferguson, Annette; Irwin, Mike; Tanvir, Nial; McConnachie, Alan; Ibata, Rodrigo; Chapman, Scott; Lewis, Geraint (2010-05-20)
    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 ...
  • The M33 Globular Cluster System with PAndAS Data: The Last Outer Halo Cluster? 

    Cockcroft, Robert; Harris, William E.; Ferguson, Annette M. N.; Huxor, Avon; Ibata, Rodrigo; Irwin, Mike J.; McConnachie, Alan W.; Woodley, Kristin A.; Chapman, Scott C.; Lewis, Geraint F.; Puzia, Thomas H. (2011-01-12)
    We use CFHT/MegaCam data to search for outer halo star clusters in M33 as part of the Pan-Andromeda Archaeological Survey (PAndAS). This work extends previous studies out to a projected radius of 50 kpc and covers over 40 ...
  • A trio of new Local Group galaxies with extreme properties 

    McConnachie, Alan; Huxor, Avon; Martin, Nicolas; Irwin, Mike; Chapman, Scott; Fahlman, Gregory; Ferguson, Annette; Ibata, Rodrigo; Lewis, Geraint; Richer, Harvey; Tanvir, Nial (2008-12)
    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 ...
