The Magellanic Clouds as a template for the study of stellar populations and galaxy interactions
M. -R. L. Cioni, K. Bekki, G. Clementini +18
The Magellanic System represents one of the best places to study the formation and evolution of galaxies. Photometric surveys of various depths, areas and wavelengths have had a si…
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…
From young massive star cluster to old globular: the L_V-sigma_0 relationship as a diagnostic tool
R. de Grijs, M. I. Wilkinson, C. N. Tadhunter
We present a new analysis of the properties of the young massive star clusters, which demonstrates that these objects are plausible progenitors of old globular clusters (GCs). The…
Mass segregation in rich clusters in the Large Magellanic Cloud - III. Implications for the initial mass function
R. de Grijs, G. F. Gilmore, A. D. Mackey +4
The distribution of core radii of rich clusters in the Large Magellanic Cloud (LMC) systematically increases in both upper limit and spread with increasing cluster age. Cluster-to-…
Analysis of colour-magnitude diagrams of rich LMC clusters: NGC 1831
L. O. Kerber, B. X. Santiago, R. Castro +1
We present the analysis of a deep colour-magnitude diagram (CMD) of NGC 1831, a rich star cluster in the LMC. The data were obtained with HST/WFPC2 in the F555W (~V) and F814W (~I)…
First Clear Signature of an Extended Dark Matter Halo in the Draco Dwarf Spheroidal
Jan T. Kleyna, Mark I. Wilkinson, N. Wyn Evans +1
We present the first clear evidence for an extended dark matter halo in the Draco dwarf spheroidal galaxy based on a sample of new radial velocities for 159 giant stars out to larg…
Dark Matter in Dwarf Spheroidals I: Models
M. I. Wilkinson, J. Kleyna, N. W. Evans +1
This paper introduces a new two-parameter family of dwarf spheroidal (dSph) galaxy models. The density distribution has a Plummer profile and falls like the inverse fourth power of…
