The radial velocity dispersion profile of the Galactic halo : constraining the density profile of the dark halo of the Milky Way
We have compiled a new sample of 240 halo objects with accurate distance and radial velocity measurements, including globular clusters, satellite galaxies, field blue horizontal branch (FHB) stars
The DART Imaging And CaT Survey of the Fornax Dwarf Spheroidal Galaxy
Aims. As part of the DART project we have used the ESO ESO/2.2m Wide Field Imager in conjunction with the VLT/FLAMES(star star) GIRAFFE spectrograph to study the detailed properties of the resolved
We present VLT FLAMES spectroscopic observations (R similar to 6500) in the Ca II triplet region for 470 probable kinematic members of the Sculptor (Scl) dwarf spheroidal galaxy. The accurate
Two Distinct Ancient Components in the Sculptor Dwarf Spheroidal Galaxy: First Results from the Dwarf Abundances and Radial Velocities Team
We have found evidence for the presence of two distinct ancient stellar components (bothgreater than or equal to10 Gyr old) in the Sculptor dwarf spheroidal galaxy. We used the ESO Wide Field Imager
A new view of the dwarf spheroidal satellites of the Milky Way from VLT flames: Where are the very metal-poor stars?
As part of the Dwarf galaxies Abundances and Radial-velocities Team (DART) program, we have measured the metallicities of a large sample of stars in four nearby dwarf spheroidal galaxies (dSph's):
The star formation and chemical evolution history of the Fornax dwarf spheroidal galaxy
We have combined deep photometry in the B, V and I bands from CTIO/MOSAIC of the Sculptor dwarf spheroidal galaxy, going down to the oldest main sequence turn-offs, with spectroscopic metallicity
A high-resolution VLT/FLAMES study of individual stars in the centre of the Fornax dwarf spheroidal galaxy
For the first time we show the detailed, late-stage, chemical evolution history of a small nearby dwarf spheroidal galaxy in the Local Group. We present the results of a high-resolution (R ~ 20 000,
The NIR Ca II triplet at low metallicity: Searching for extremely low-metallicity stars in classical dwarf galaxies
The NIR Ca II triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group, providing a better understanding of
Extremely metal-poor stars in classical dwarf spheroidal galaxies: Fornax, Sculptor, and Sextans
We present the results of a dedicated search for extremely metal-poor stars in the Fornax, Sculptor, and Sextans dSphs. Five stars were selected from two earlier VLT/Giraffe and HET/HRS surveys and
