Inside the whale: the structure and dynamics of the isolated Cetus dwarf spheroidal
G. F. Lewis, R. A. Ibata, S. C. Chapman +4
This paper presents a study of the Cetus dwarf, an isolated dwarf galaxy within the Local Group. A matched-filter analysis of the INT/WFC imaging of this system reveals no evidence…
Numerical simulations of the metallicity distribution in dwarf spheroidal galaxies
E. Ripamonti, E. Tolstoy, A. Helmi +2
Recent observations show that the number of stars with very low metallicities in the dwarf spheroidal satellites of the Milky Way is low, despite the low average metallicities of s…
A new view of the dwarf spheroidal satellites of the Milky Way from VLT/FLAMES: Where are the very metal poor stars?
Amina Helmi, M. J. Irwin, E. Tolstoy +13
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 ga…
The stellar content of the isolated transition dwarf galaxy DDO210
Alan W. McConnachie, Nobuo Arimoto, Mike Irwin +1
We use Subaru Suprime-Cam and VLT FORS1 photometry of the dwarf galaxy DDO210 to study the global stellar content and structural properties of a transition-type galaxy (with proper…
The DART imaging and CaT survey of the Fornax Dwarf Spheroidal Galaxy
G. Battaglia, E. Tolstoy, A. Helmi +13
As part of the DART project we have used the ESO/2.2m Wide Field Imager in conjunction with the VLT/FLAMES GIRAFFE spectrograph to study the detailed properties of the resolved ste…
Resolved Stellar Populations at the Distance of Virgo
Eline Tolstoy
Top of the wish list of any astronomer who wants to understand galaxy formation and evolution is to resolve the stellar populations of a sample of giant elliptical galaxies: to tak…
VLT/UVES Spectroscopy of Individual Stars in Three Globular Clusters in the Fornax Dwarf Spheroidal Galaxy
Bruno Letarte, Vanessa Hill, Pascale Jablonka +3
We present a high resolution (R ~ 43000) abundance analysis of a total of nine stars in three of the five globular clusters associated with the nearby Fornax dwarf spheroidal galax…
