Theoretical models of the halo occupation distribution: Separating central and satellite galaxies
formation halos
2014/12/24
The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at the centers of halos...
The growth of central and satellite galaxies in cosmological smoothed particle hydrodynamics simulations
theory formation
2014/12/23
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7 × 109 M⊙. Most frien...

2011/9/26
We investigate the properties of satellite galaxies that surround isolated hosts within the redshift range 0.01 < z < 0.15, using data taken as part of the Galaxy And Mass Assembly survey. Making use ...

2010/11/15
We present a wide field survey of satellite galaxies in M106 (NGC 4258)covering a 1.7◦ × 2◦ field around M106 using Canada-France-Hawaii Tele-scope/MegaCam. We find 16 satellite galaxy can...
The Elemental Abundance Distributions of Milky Way Satellite Galaxies
Elemental Abundance Distributions Milky Way Satellite Galaxies
2010/11/11
The chemical compositions of the stars in Milky Way (MW)satellite galaxies reveals the history of gas flows and star formation (SF)intensity. This talk presented a Keck/DEIMOS spectroscopic survey of ...
The preferred direction of infalling satellite galaxies in the Local Group
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/27
Using a high resolution DM simulation of the Local Group (LG), conducted within the framework of the Constrained Local UniversE Simulation (CLUES) project, we investigate the nature of how satellites ...
A recent study of the satellite galaxies surrounding the Milky Way casts doubt on existing models of dark matter — according to its authors in Germany, Austria and Australia. The locations of the gala...
