Selection of Metal-poor Giant Stars Using the Sloan Digital Sky Survey Photometric System
A. Helmi, Z. Ivezic, F. Prada +10
We present a method for photometric selection of metal-poor halo giants from the imaging data of the Sloan Digital Sky Survey (SDSS). These stars are offset from the stellar locus…
The phase-space structure of cold dark-matter halos: Insights into the Galactic halo
Amina Helmi, Simon D. M. White, Volker Springel
We study the formation of the Milky Way's halo in a CDM cosmology by scaling down a high resolution simulation of the formation of a cluster of galaxies. We determine how much p…
The phase-space structure of a dark-matter halo: Implications for dark-matter direct detection experiments
Amina Helmi, Simon D. M. White, Volker Springel
We study the phase-space structure of a dark-matter halo formed in a high resolution simulation of a Lambda CDM cosmology. Our goal is to quantify how much substructure is left ove…
