The Open Cluster Chemical Abundances and Mapping Survey: VI. Galactic Chemical Gradient Analysis from APOGEE DR17
Natalie Myers, John Donor, Taylor Spoo +19
The goal of the Open Cluster Chemical Abundances and Mapping (OCCAM) survey is to constrain key Galactic dynamic and chemical evolution parameters by the construction and analysis…
How well do local relations predict gas-phase metallicity gradients? Results from SDSS-IV MaNGA
Nicholas F. Boardman, Gail Zasowski, Jeffrey A. Newman +8
Gas-phase metallicity gradients in galaxies provide important clues to those galaxies' formation histories. Using SDSS-IV MaNGA data, we previously demonstrated that gas metallicit…
The Milky Way tomography with APOGEE: intrinsic density distribution and structure of mono-abundance populations
Jianhui Lian, Gail Zasowski, Ted Mackereth +11
The spatial distribution of mono-abundance populations (MAPs, selected in [Fe/H] and [Mg/Fe]) reflect the chemical and structural evolution in a galaxy and impose strong constraint…
The chemical characterisation of halo substructure in the Milky Way based on APOGEE
Danny Horta, Ricardo P. Schiavon, J. Ted Mackereth +21
Galactic haloes in a -CDM universe are predicted to host today a swarm of debris resulting from cannibalised dwarf galaxies. The chemo-dynamical information recorded in their st…
Quantifying radial migration in the Milky Way: Inefficient over short timescales but essential to the very outer disc beyond ~15 kpc
Jianhui Lian, Gail Zasowski, Sten Hasselquist +10
Stellar radial migration plays an important role in reshaping a galaxy's structure and the radial distribution of stellar population properties. In this work, we revisit reported o…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
