  • 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 ...

  • Discovery and analysis of three faint dwarf galaxies and a globular cluster in the outer halo of the Andromeda galaxy 

    Martin, N. F.; Ibata, R. A.; Irwin, M. J.; Chapman, S.; Lewis, G. F.; Ferguson, A. M. N.; Tanvir, N.; McConnachie, A. W. (2006-10-01)
    We present the discovery of three faint dwarf galaxies and a globular cluster in the halo of the Andromeda galaxy (M31), found in our MegaCam survey that spans the southern quadrant of M31, from a projected distance of ~50 ...

  • The Haunted Halos of Andromeda and Triangulum: A panorama of galaxy formation in action 

    Ibata, R.; Martin, N. F.; Irwin, M.; Chapman, S.; Ferguson, A. M. N.; Lewis, G. F.; McConnachie, A. W. (2007-12-20)
    We present a deep photometric survey of M31, conducted with the CFHT and INT, covering the inner 50 kpc of the galaxy, the Southern quadrant out to 150 kpc, and extending to M33. This is the first systematic panoramic study ...

  • The next generation virgo cluster survey (NGVS). I. Introduction to the survey 

    Ferrarese, L.; Cote, P.; Cuillandre, J. -C; Gwyn, S. D. J.; Peng, E. W.; MacArthur, L. A.; Duc, P. -A; Boselli, A.; Mei, S.; Erben, T.; McConnachie, A. W.; Durrell, P. R.; Mihos, J. C.; Jordan, A.; Lancon, A.; Puzia, T. H.; Emsellem, E.; Balogh, M. L.; Blakeslee, J. P.; van Waebeke, L.; Gavazzi, R.; Vollmer, B.; Kavelaars, J. J.; Woods, D.; Ball, N. M.; Boissier, S.; Courteau, S.; Ferriere, E.; Gavazzi, G.; Hildebrandt, H.; Hudelot, P.; Huertas-Company, M.; Liu, C.; McLaughlin, D.; Mellier, Y.; Milkeraitis, M.; Schade, D.; Balkowski, C.; Bournaud, F.; Carlberg, R. G.; Chapman, S. C.; Hoekstra, H.; Peng, C.; Sawicki, M.; Simard, L.; Taylor, J. E.; Tully, R. B.; van Driel, W.; Wilson, C. D.; Burdullis, T.; Mahoney, B.; Manset, N. (2012)

  • The Recent Stellar Archeology of M31 - The Nearest Red Disk Galaxy 

    Davidge, T. J.; McConnachie, A. W.; Fardal, M. A.; Fliri, J.; Valls-Gabaud, D.; Chapman, S. C.; Lewis, G. F.; Rich, R. M. (2012-03-27)
    We examine the star-forming history (SFH) of the M31 disk during the past few hundred Myr. The luminosity functions (LFs) of main sequence stars at distances R_GC > 21 kpc (i.e. > 4 disk scale lengths) are matched by models ...

  • The scatter about the "Universal" dwarf spheroidal mass profile: A kinematic study of the M31 satellites, And V and And VI 

    Collins, M. L. M.; Chapman, S. C.; Rich, R. M.; Ibata, R. A.; Irwin, M. J.; Peñarrubia, J.; Arimoto, N.; Brooks, A. M.; Ferguson, A. M. N.; Lewis, G. F.; McConnachie, A. W.; Venn, K. (2011-03-10)
    While the satellites of the Milky Way (MW) have been shown to be largely consistent in terms of their mass contained within one half--light radius (M_{half}) with a "Universal" mass profile, a number of M31 satellites are ...

  • A spectroscopic survey of EC4, an Extended Cluster in Andromeda's halo 

    Collins, M. L. M.; Chapman, S. C.; Irwin, M.; Ibata, R.; Martin, N. F.; Ferguson, A. M. N.; Huxor, A.; Lewis, G. F.; Mackey, A. D.; McConnachie, A. W.; Tanvir, N. (2009-03-26)
    We present a spectroscopic survey of candidate red giant branch stars in the extended star cluster, EC4, discovered in the halo of M31 from our CFHT/MegaCam survey, overlapping the tidal streams, Stream Cp and Stream Cr. ...

  • 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 ...
