The large-scale structure of the halo of the Andromeda Galaxy Part I: global stellar density, morphology and metallicity properties
Rodrigo A. Ibata, Geraint F. Lewis, Alan W. McConnachie +14
We present an analysis of the large-scale structure of the halo of the Andromeda galaxy, based on the Pan-Andromeda Archeological Survey (PAndAS), currently the most complete map o…
The PAndAS view of the Andromeda satellite system - I. A Bayesian search for dwarf galaxies using spatial and color-magnitude information
Nicolas F. Martin, Rodrigo A. Ibata, Alan W. McConnachie +5
We present a generic algorithm to search for dwarf galaxies in photometric catalogs and apply it to the Pan-Andromeda Archaeological Survey (PAndAS). The algorithm is developed in…
A peculiar faint satellite in the remote outer halo of M31
Dougal Mackey, Avon Huxor, Nicolas Martin +9
We present Hubble Space Telescope imaging of a newly-discovered faint stellar system, PAndAS-48, in the outskirts of the M31 halo. Our photometry reveals this object to be comprise…
