TL;DR
APOGEE is a high-resolution near-infrared spectroscopic survey of Galactic stars, aiming to map chemical abundances and dynamics across all Galactic components, overcoming dust obscuration.
Contribution
It introduces a large-scale, high-resolution NIR survey with a dedicated spectrograph to provide comprehensive chemical and kinematic data for Milky Way stars.
Findings
Survey will observe ~100,000 giant stars with high S/N.
Provides the first uniform chemical abundance database across Galactic populations.
Aims to elucidate the Milky Way's formation and evolution processes.
Abstract
APOGEE is a large-scale, NIR, high-resolution (R~20,000) spectroscopic survey of Galactic stars. It is one of the four experiments in SDSS-III. Because APOGEE will observe in the H band, it will be the first survey to pierce through Galactic dust and provide a vast, uniform database of chemical abundances and radial velocities for stars across all Galactic populations (bulge, disk, and halo). The survey will be conducted with a dedicated, 300-fiber, cryogenic, spectrograph that is being built at the University of Virginia, coupled to the ARC 2.5m telescope at Apache Point Observatory. APOGEE will use a significant fraction of the SDSS-III bright time during a three-year period to observe, at high signal-to-noise ratio (S/N>100), about 100,000 giant stars selected directly from 2MASS down to a typical flux limit of H<13. The main scientific objectives of APOGEE are: (1) measuring…
