Cores and Cusps in the Dwarf Spheroidals
N. W. Evans, J. An, M. G. Walker
We consider the problem of determining the structure of the dark halo of nearby dwarf spheroidal galaxies (dSphs) from the spherical Jeans equations. Whether the dark halos are cus…
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…
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…
Further Evidence for a Merger Origin for the Thick Disk: Galactic Stars Along Lines-of-sight to Dwarf Spheroidal Galaxies
Rosemary F. G. Wyse, Gerard Gilmore, John E. Norris +5
The history of the Milky Way Galaxy is written in the properties of its stellar populations. Here we analyse stars observed as part of surveys of local dwarf spheroidal galaxies, b…
Ursa Major: a missing low-mass CDM halo?
J. T. Kleyna, M. I. Wilkinson, N. W. Evans +1
The recently discovered Ursa Major dwarf spheroidal (dSph) galaxy candidate is about five to eight times less luminous than the faintest previously known dSphs And IX, Draco, and U…
Distant Field BHB Stars III: Identification of a probable outer halo stream at Galactocentric distance r = 70 kpc
L. Clewley, S. J. Warren, P. C. Hewett +3
We present VLT-FORS1 spectra of a sample of 34 faint 20.0 < g* < 21.1 A-type stars selected from the Sloan Digital Sky Survey Early Data Release, with the goal of measuring the vel…
