Andromeda XVII: A New Low Luminosity Satellite of M31
Mike Irwin, Annette Ferguson, Avon Huxor +3
We report the discovery of a new dwarf spheroidal galaxy near M31 based on INT/WFC imaging. The system, Andromeda XVII (And XVII), is located at a projected radius of ~44 kpc from…
Kinematic and Chemical constraints on the formation of M31's inner and outer halo
A. Koch, R. M. Rich, D. B. Reitzel +8
The halo of M31 shows a wealth of substructures that are consistent with satellite accretion. Here we report on kinematic and abundance results from Keck/DEIMOS spectroscopy in the…
The three dimensional structure of the giant stellar stream in Andromeda
A. W. McConnachie, M. J. Irwin, R. A. Ibata +3
The wide-field CCD camera at the CFH telescope was used to survey the giant stellar stream in the Andromeda galaxy, resolving stars down the red giant branch in M31 to I ~ 25, a ma…
