The Nature and Origin of Substructure in the Outskirts of M31 -- II. Detailed Star Formation Histories
Edouard J. Bernard, Annette M. N. Ferguson, Jenny C. Richardson +9
While wide-field surveys of M31 have revealed much substructure at large radii, understanding the nature and origin of this material is not straightforward from morphology alone. U…
PAndAS' progeny: extending the M31 dwarf galaxy cabal
Jenny C. Richardson, Mike Irwin, Alan W. McConnachie +8
We present the discovery of five new dwarf galaxies, Andromeda XXIII-XXVII, located in the outer halo of M31. These galaxies were found in the second year of data from the Pan-Andr…
An HST/ACS View of the Inhomogeneous Outer Halo of M31
J. C. Richardson, A. M. N. Ferguson, A. D. Mackey +6
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/…
Multiple stellar populations in three rich Large Magellanic Cloud star clusters
A. D. Mackey, P. Broby Nielsen, A. M. N. Ferguson +1
We present deep colour-magnitude diagrams for three rich intermediate-age star clusters in the Large Magellanic Cloud, constructed from archival ACS F435W and F814W imaging. All th…
The Nature and Origin of Substructure in the Outskirts of M31. I. Surveying the Stellar Content with HST/ACS
J. C. Richardson, A. M. N. Ferguson, R. A. Johnson +6
We present the largest and most detailed survey to date of the stellar populations in the outskirts of M31 based on the analysis of 14 deep HST/ACS pointings spanning the range 11.…
