Chemical Evolution in the Carina Dwarf Spheroidal
A. Koch, E. K. Grebel, D. Harbeck +5
We present metallicities for 487 red giants in the Carina dwarf spheroidal (dSph) galaxy that were obtained from FLAMES low-resolution Ca triplet (CaT) spectroscopy. We find a mean…
Spectroscopic survey of the Galaxy with Gaia I. Design and performance of the Radial Velocity Spectrometer
D. Katz, U. Munari, M. Cropper +22
The definition and optimisation studies for the Gaia satellite spectrograph, the Radial Velocity Spectrometer (RVS), converged in late 2002 with the adoption of the instrument base…
A photometrically and kinematically distinct core in the Sextans dwarf spheroidal galaxy
J. T. Kleyna, M. I. Wilkinson, N. W. Evans +1
We present the line of sight radial velocity dispersion profile of the Sextans dwarf spheroidal galaxy (dSph), based on a sample of 88 stars extending to about 1 degree (about 1.5…
Kinematically Cold Populations at Large Radii in the Draco and Ursa Minor Dwarf Spheroidals
M. I. Wilkinson, J. T. Kleyna, N. W. Evans +3
We present projected velocity dispersion profiles for the Draco and Ursa Minor (UMi) dwarf spheroidal galaxies based on 207 and 162 discrete stellar velocities, respectively. Both…
On the Origin of Dark Matter Cores in Dwarf Galaxies
Massimo Ricotti, Mark I. Wilkinson
In this paper, we study the dynamical stability and time evolution of the central dark matter cores of low-mass (about 10^8-10^9 M_solar) galactic haloes found in recent cold dark…
