The DESI Experiment Part II: Instrument Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift…
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through…
Bright Metal-Poor Stars from the Hamburg/ESO Survey. II. A Chemodynamical Analysis
Timothy C. Beers, Vinicius M. Placco, Daniela Carollo +6
We obtain estimates of stellar atmospheric parameters for a previously published sample of 1777 relatively bright (9 < B < 14) metal-poor candidates from the Hamburg/ESO Survey. Th…
APOGEE Chemical Abundances of Globular Cluster Giants in the Inner Galaxy
Ricardo P. Schiavon, Jennifer A. Johnson, Peter M. Frinchaboy +27
We report chemical abundances obtained by SDSS-III/APOGEE for giant stars in five globular clusters located within 2.2 kpc of the Galactic centre. We detect the presence of multipl…
Chemical trends in the Galactic Halo with APOGEE data
E. Fernández-Alvar, L. Carigi, C. Allende Prieto +10
The galaxy formation process in the -Cold Dark Matter scenario can be constrained from the analysis of stars in the Milky Way's halo system. We examine the variation of chemical…
Observational Constraints on First-Star Nucleosynthesis. II. Spectroscopy of an Ultra Metal-Poor CEMP-no Star
Vinicius M. Placco, Anna Frebel, Timothy C. Beers +6
We report on the first high-resolution spectroscopic analysis of HE0020-1741, a bright (V=12.9), ultra metal-poor ([Fe/H] = -4.1), carbon-enhanced ([C/Fe] = +1.7) star selected fro…
