The Milky Way’s Circular Velocity Curve to 60 kpc and an Estimate of the Dark Matter Halo Mass from the Kinematics of ~2400 SDSS Blue Horizontal-Branch Stars
- X.-X. Xue, H. Rix, +14 authors D. Schneider
- Physics
- 8 January 2008
We derive new constraints on the mass of the Milky Way's dark matter halo, based on 2401 rigorously selected blue horizontal-branch halo stars from SDSS DR6. This sample enables construction of the… Expand
Constraints on the relationship between stellar mass and halo mass at low and high redshift
- B. Moster, R. Somerville, +4 authors L. Oser
- Physics
- 27 March 2009
We use a statistical approach to determine the relationship between the stellar masses of galaxies and the masses of the dark matter halos in which they reside. We obtain a parameterized… Expand
Galaxy Groups in the SDSS DR4. I. The Catalog and Basic Properties
We use a modified version of the halo-based group finder developed by Yang et al. to select galaxy groups from the Sloan Digital Sky Survey (SDSS DR4). In the first step, a combination of two methods… Expand
Concentration, spin and shape of dark matter haloes as a function of the cosmological model: WMAP1, WMAP3 and WMAP5 results
- A. Maccio', A. Dutton, F. Bosch
- Physics
- 14 May 2008
We investigate the effects of changes in the cosmological parameters between the Wilkinson Microwave Anisotropy Probe (WMAP) 1st, 3rd and 5th year results on the structure of dark matter haloes. We… Expand
Concentration, spin and shape of dark matter haloes: Scatter and the dependence on mass and environment
- A. Maccio', A. Dutton, F. Bosch, B. Moore, Doug PotterJoachim Stadel
- Physics
- 7 August 2006
We use a series of cosmological N-body simulations for a flat A cold dark matter (ACDM) cosmology to investigate the structural properties of dark matter haloes, at redshift zero, in the mass range 3… Expand

Properties of galaxy groups in the Sloan Digital Sky Survey – I. The dependence of colour, star formation and morphology on halo mass
- S. Weinmann, F. Bosch, X. Yang, H. Mo
- Physics
- 6 September 2005
Using a large galaxy group catalogue constructed from the Sloan Digital Sky Survey Data Release 2, we investigate the correlation between various galaxy properties and halo mass. We split the… Expand
Galaxy evolution in groups and clusters: satellite star formation histories and quenching time-scales in a hierarchical Universe
Satellite galaxies in groups and clusters are more likely to have low star formation rates (SFR) and lie on the red-sequence than central (field) galaxies. Using galaxy group/cluster catalogs from… Expand
Galaxy Groups in the SDSS DR4. III. The Luminosity and Stellar Mass Functions
Using a large galaxy group catalog constructed from the Sloan Digital Sky Survey Data Release 4 (SDSS DR4) with an adaptive halo-based group finder, we investigate the luminosity and stellar mass… Expand
