Metal-Poor Lithium-Rich Giants in the Radial Velocity Experiment Survey
Gregory R. Ruchti, Jon P. Fulbright, Rosemary F. G. Wyse +17
We report the discovery of eight lithium-rich field giants found in a high resolution spectroscopic sample of over 700 metal-poor stars ([Fe/H]<-0.5) selected from the RAVE survey.…
The Origin of Disks and Spheroids in Simulated Galaxies
Laura V. Sales, Julio F. Navarro, Tom Theuns +5
In the simplest scenario, disk galaxies form predominantly in halos with high angular momentum and quiet recent assembly history, whereas spheroids are the slowly-rotating remnants…
The Aquila comparison Project: The Effects of Feedback and Numerical Methods on Simulations of Galaxy Formation
C. Scannapieco, M. Wadepuhl, O. H. Parry +20
We compare the results of thirteen cosmological gasdynamical codes used to simulate the formation of a galaxy in the LCDM structure formation paradigm. The various runs differ in t…
The dark matter halos of dwarf galaxies: a challenge for the LCDM paradigm?
Ismael Ferrero, Mario G. Abadi, Julio F. Navarro +2
The cold dark matter halo mass function is much steeper than the galaxy stellar mass function on galactic and subgalactic scales. This difference is usually reconciled by assuming…
The RAVE catalogue of stellar elemental abundances: first data release
C. Boeche, A. Siebert, M. Williams +21
We present chemical elemental abundances for stars observed by the RAdial Velocity Experiment (RAVE), an ambitious spectroscopic survey of our Galaxy at Galactic latitudes…
Distance determination for RAVE stars using stellar models III: The nature of the RAVE survey and Milky Way chemistry
B. Burnett, J. Binney, S. Sharma +19
We apply the method of Burnett & Binney (2010) for the determination of stellar distances and parameters to the internal catalogue of the Radial Velocity Experiment (Steinmetz et a…
Observational Properties of the Metal-Poor Thick Disk of the Milky Way Galaxy and Insights into Its Origins
Gregory R. Ruchti, Jon P. Fulbright, Rosemary F. G. Wyse +17
We have undertaken the study of the elemental abundances and kinematic properties of a metal-poor sample of candidate thick-disk stars selected from the RAVE spectroscopic survey o…
Single-lined Spectroscopic Binary Star Candidates in the RAVE Survey
G. Matijevic, T. Zwitter, O. Bienayme +16
Repeated spectroscopic observations of stars in the Radial Velocity Experiment (RAVE) database are used to identify and examine single-lined binary (SB1) candidates. The RAVE lates…
Clues to the "Magellanic Galaxy" from Cosmological Simulations
Laura V. Sales, Julio F. Navarro, Andrew P. Cooper +3
We use cosmological simulations from the Aquarius Project to study the orbital history of the Large Magellanic Cloud (LMC) and its potential association with other satellites of th…
The RAdial Velocity Experiment (RAVE): Third Data Release
A. Siebert, M. E. K. Williams, A. Siviero +36
We present the third data release of the RAdial Velocity Experiment (RAVE) which is the first milestone of the RAVE project, releasing the full pilot survey. The catalog contains 8…
The Shape of Dark Matter Haloes in the Aquarius Simulations: Evolution and Memory
Carlos A. Vera-Ciro, Laura V. Sales, Amina Helmi +5
We use the high resolution cosmological N-body simulations from the Aquarius project to investigate in detail the mechanisms that determine the shape of Milky Way-type dark matter…
The population of Milky Way satellites in the LambdaCDM cosmology
Andreea S. Font, Andrew J. Benson, Richard G. Bower +11
We present a model for the satellites of the Milky Way in which galaxy formation is followed using semi-analytic techniques applied to the six high-resolution N-body simulations of…
Density Variations in the NW Star Stream of M31
R. G. Carlberg, Harvey B. Richer, Alan W. McConnachie +10
The Pan Andromeda Archeological Survey (PAndAS) CFHT Megaprime survey of the M31-M33 system has found a star stream which extends about 120 kpc NW from the center of M31. The great…
A Sagittarius-Induced Origin for the Monoceros Ring
Leo Michel-Dansac, Mario G. Abadi, Julio F. Navarro +1
The Monoceros ring is a collection of stars in nearly-circular orbits at roughly 18 kpc from the Galactic center. It may have originated (i) as the response of the disc to perturba…
The Density and Pseudo-Phase-Space Density Profiles of CDM halos
Aaron D. Ludlow, Julio F. Navarro, Michael Boylan-Kolchin +4
Cosmological N-body simulations indicate that the spherically-averaged density profiles of cold dark matter halos are accurately described by Einasto profiles, where the logarithmi…
Substructure in the stellar halos of the Aquarius simulations
Amina Helmi, A. P. Cooper, S. D. M. White +3
We characterize substructure in the simulated stellar halos of Cooper et al. (2010) which were formed by the disruption of satellite galaxies within the cosmological N-body simulat…
