  • The Discovery of Remote Globular Clusters in M33 

    Huxor, A., A. M. N. Ferguson, M. K. Barker, N. R. Tanvir, et al. 2009. "The Discovery of Remote Globular Clusters in M33." The Astrophysical Journal Letters, 698(2): 77-L81
    We present the discovery of four remote star clusters in M33, one of which is of an extended nature. Three of the clusters were discovered using survey data from the Isaac Newton Telescope Wide-Field Camera while one was ...

  • The nature of the bright submillimeter galaxy population: a radio pre-selected sample with I>25 

    Chapman, S. C., E. Richards, G. Lewis, G. Wilson, et al. 2001. "The nature of the bright submillimeter galaxy population: a radio pre-selected sample with I>25." The Astrophysical Journal 548(2): 147-L151
    Deep submillimetre surveys have successfully detected distant, star-forming galaxies, enshrouded in vast quantities of dust and which emit most of their energy at far infrared wavelengths. These luminous galaxies are an ...

  • On the accretion origin of a vast extended stellar disk around the Andromeda galaxy 

    Ibata, R., S. Chapman, A. M. N. Ferguson, G. Lewis, et al. 2005. "On the accretion origin of a vast extended stellar disk around the Andromeda galaxy." The Astrophysical Journal 634(1): 287-313
    We present the discovery of an inhomogenous, low-surface brightness, extended disk-like structure around the Andromeda galaxy (M31) based on a large kinematic survey of more than 2800 stars with the Keck/DEIMOS spectrograph. ...

  • Taking measure of the Andromeda halo: a kinematic analysis of the giant stream surrounding M31 

    Ibata, R., S. Chapman, A. M. N. Ferguson, M. Irwin, et al. 2004. "Taking measure of the Andromeda halo: a kinematic analysis of the giant stream surrounding M31." Monthly Notices of the Royal Astronomical Society 351(1): 117-124
    We present a spectroscopic survey of the giant stellar stream found in the halo of the Andromeda galaxy. Taken with the DEIMOS multi-object spectrograph on the Keck2 telescope, these data display a narrow velocity dispersion ...

  • The tidal trail of NGC205? 

    McConnachie, A., M. Irwin, G. Lewis, R. Ibata, et al. 2004. "The tidal trail of NGC205?." Monthly Notices of the Royal Astronomical Society 351(4): 94-L98
    Using data taken as part of the Isaac Newton Telescope Wide Field Camera (INT WFC) survey of M31, we have identified an arc-like overdensity of blue, presumably metal-poor, red giant branch stars in the north-west quadrant ...
