Galactic stellar haloes in the CDM model
A. P. Cooper, S. Cole, C. S. Frenk +9
We present six simulations of galactic stellar haloes formed by the tidal disruption of accreted dwarf galaxies in a fully cosmological setting. Our model is based on the Aquarius…
PAndAS' cubs: discovery of two new dwarf galaxies in the surroundings of the Andromeda and Triangulum galaxies
Nicolas F. Martin, Alan W. McConnachie, Mike Irwin +10
We present the discovery of two new dwarf galaxies, Andromeda XXI and Andromeda XXII, located in the surroundings of the Andromeda and Triangulum galaxies (M31 and M33). These disc…
The earliest stars and their relics in the Milky Way
L. Gao, Tom Theuns, C. S. Frenk +4
We have implemented a simple model to identify the likely sites of the first stars and galaxies in the high-resolution simulations of the formation of galactic dark matter halos of…
RAVE spectroscopy of luminous blue variables in the Large Magellanic Cloud
U. Munari, A. Siviero, O. Bienaymé +19
CONTEXT: The RAVE spectroscopic survey for galactic structure and evolution obtains 8400-8800 Ang spectra at 7500 resolving power at the UK Schmidt Telescope using the 6dF multi-fi…
Galaxy-Induced Transformation of Dark Matter Halos
Mario G. Abadi, Julio F. Navarro, Mark Fardal +2
We use N-body/gasdynamical LambdaCDM cosmological simulations to examine the effect of the assembly of a central galaxy on the shape and mass profile of its dark halo. Two series o…
