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-L81We 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 ... -
An HST/ACS View of the Inhomogeneous Outer Halo of M31
Richardson, J. C., A. M. N. Ferguson, A. D. Mackey, M. J. Irwin, et al. 2009. "An HST/ACS View of the Inhomogeneous Outer Halo of M31." Monthly Notices of the Royal Astronomical Society 396:1842.We present a high precision photometric view of the stellar populations in the outer halo of M31, using data taken with the Hubble Space Telescope Advanced Camera for Surveys (HST/ACS). We analyse the field populations ... -
The kinematic footprints of five stellar streams in Andromeda's halo
Chapman, S. C., R. Ibata, M. Irwin, A. Koch, et al. 2008. "The kinematic footprints of five stellar streams in Andromeda's halo." Monthly Notices of the Royal Astronomical Society 390(4): 1437(abridged) We present a spectroscopic analysis of five stellar streams (`A', `B', `Cr', `Cp' and `D') as well as the extended star cluster, EC4, which lies within streamC, all discovered in the halo of M31 from our ... -
A spectroscopic survey of EC4, an Extended Cluster in Andromeda's halo
Collins, M. L. M., S. C. Chapman, M. Irwin, R. Ibata, et al. 2009. "A spectroscopic survey of EC4, an Extended Cluster in Andromeda's halo." Monthly Notices of the Royal Astronomical Society 396: 1619.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. ...
