Tracing Galaxy Formation with Stellar Halos II: Relating Substructure in Phase- and Abundance-Space to Accretion Histories
Kathryn V. Johnston, James S. Bullock, Sanjib Sharma +3
This paper explores the mapping between the observable properties of a stellar halo in phase- and abundance-space and the parent galaxy's accretion history in terms of the characte…
The accretion origin of the Milky Way's stellar halo
Eric F. Bell, Daniel B. Zucker, Vasily Belokurov +15
We have used data from the Sloan Digital Sky Survey (SDSS) Data Release 5 to explore the overall structure and substructure of the stellar halo of the Milky Way using about 4 milli…
The Angular Momentum Distribution of Gas and Dark Matter in Galactic Halos
Sanjib Sharma, Matthias Steinmetz
(Abridged) We report results of a series of non radiative N-body/SPH simulations in a LCDM cosmology. We find that the spin of the baryonic component is on average larger than that…
