The Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) survey is a photometric survey designed to study systematically cosmic...
An absolute calibration of DENIS (deep near infrared southern sky survey)
An absolute calibration of the DENIS photometric system is presented. It includes the determination of the overall transmission profiles in the 3 bands, namely...
An Intermediate-age Alpha-rich Galactic Population in K2
We explore the relationships between the chemistry, ages, and locations of stars in the Galaxy using asteroseismic data from the K2 mission and spectroscopic...
Anomalously Low-metallicity Regions in MaNGA Star-forming Galaxies: Accretion Caught in Action?
We use data from 1222 late-type star-forming galaxies in the SDSS IV Mapping Nearby Galaxies at Apache Point Observatory survey to identify regions in which the...
Aperture corrections for disk galaxy properties derived from the CALIFA survey. Balmer emission lines in spiral galaxies
This work investigates the effect of the aperture size on derived galaxy properties for which we have spatially-resolved optical spectra. We focus on some...
APOGEE Data Releases 13 and 14: Stellar Parameter and Abundance Comparisons with Independent Analyses
Data from the SDSS-IV/Apache Point Observatory Galactic Evolution Experiment (APOGEE-2) have been released as part of SDSS Data Releases 13 (DR13) and 14 (DR14)...
APOGEE Kinematics. I. Overview of the Kinematics of the Galactic Bulge as Mapped By APOGEE
We present the stellar kinematics across the Galactic bulge and into the disk at positive longitudes from the SDSS-III APOGEE spectroscopic survey of the Milky...
The second phase of the APOGEE survey is providing near-infrared (near-IR), high-resolution, high signal-to-noise spectra of stars in the halo, disc, bar, and...
APOGEE: The Apache Point Observatory Galactic Evolution Experiment
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...
