  • Deep Gemini/GMOS imaging of an extremely isolated globular cluster in the Local Group 

    Mackey, A. D.; Ferguson, A. M. N.; Irwin, M. J.; Martin, N. F.; Huxor, A. P.; Tanvir, N. R.; Chapman, S. C.; Ibata, R. A.; Lewis, G. F.; McConnachie, A. W. (2009-09-08)
    We report on deep imaging of a remote M31 globular cluster, MGC1, obtained with Gemini/GMOS. Our colour-magnitude diagram for this object extends ~5 magnitudes below the tip of the red giant branch and exhibits features ...

  • Exploring the Properties of the M31 Halo Globular Cluster System 

    Huxor, A. P.; Ferguson, A. M. N.; Tanvir, N. R.; Irwin, M. J.; Mackey, A. D.; Ibata, R. A.; Bridges, T.; Chapman, S. C.; Lewis, G. F. (2011-02-02)
    Following on from our discovery of a significant population of M31 outer halo globular clusters (GCs), and updates to the Revised Bologna Catalogue of M31 GCs, we investigate the GC system of M31 out to an unprecedented ...

  • The structure of star clusters in the outer halo of M31 

    Tanvir, N. R.; Mackey, A. D.; Ferguson, A. M. N.; Huxor, A. P.; Read, J. I.; Lewis, G. F.; Irwin, M. J.; Chapman, S.; Ibata, R.; Wilkinson, M. I.; McConnachie, A. W.; Martin, N. F.; Davies, M. B.; Bridges, T. J. (2012-02-09)
    We present a structural analysis of halo star clusters in M31 based on deep Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) imaging. The clusters in our sample span a range in galactocentric projected distance ...
