Is Ursa Major II the Progenitor of the Orphan Stream?
M. Fellhauer, N. W. Evans, V. Belokurov +9
Prominent in the `Field of Streams' -- the Sloan Digital Sky Survey map of substructure in the Galactic halo -- is an `Orphan Stream' without obvious progenitor. In this numerical…
Complexity on Small Scales II: Metallicities and Ages in the Leo II Dwarf Spheroidal Galaxy
A. Koch, E. K. Grebel, J. T. Kleyna +5
We present metallicities and ages for 52 red giants in the remote Galactic dwarf spheroidal (dSph) galaxy Leo II. These stars cover the entire surface area of Leo II and are radial…
Observed Properties of Dark Matter: dynamical studies of dSph galaxies
G Gilmore, M Wilkinson, J Kleyna +4
The Milky Way satellite dwarf spheroidal (dSph) galaxies are the smallest dark matter dominated systems in the universe. We have underway dynamical studies of the dSph to quantify…
The Origin of the Bifurcation in the Sagittarius Stream
M. Fellhauer, V. Belokurov, N. W. Evans +9
The latest Sloan Digital Sky Survey data reveal a prominent bifurcation in the distribution of debris of the Sagittarius dwarf spheroidal (Sgr) beginning at a right ascension of ro…
An Orphan in the "Field of Streams"
V. Belokurov, N. W. Evans, M. J. Irwin +19
We use Sloan Digital Sky Survey Data Release 5 photometry and spectroscopy to study a tidal stream that extends over 50 degrees in the North Galactic Cap. From the analysis of the…
A deep kinematic survey of planetary nebulae in the Andromeda Galaxy using the Planetary Nebula Spectrograph
H. R. Merrett, M. R. Merrifield, N. G. Douglas +13
We present a catalogue of positions, magnitudes and velocities for 3300 emission-line objects found by the Planetary Nebula Spectrograph in a survey of the Andromeda Galaxy, M31. O…
