The Gaia mission has provided an invaluable wealth of astrometric data for more than a
billion stars in our Galaxy. The synergy between Gaia astrometry, photometry, and …

APOGEE is a high-resolution (R∼ 22,000), near-infrared, multi-epoch, spectroscopic survey
of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an …

Abstract The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is a
dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a …

We investigate the inner regions of the Milky Way using data from APOGEE and Gaia EDR3.
Our inner Galactic sample has more than 26 500 stars within| X Gal|< 5 kpc,| Y Gal|< 3.5 …

Context. The analysis of the latest release of the Apache Point Observatory Galactic
Evolution Experiment project (APOGEE DR16) data suggests the existence of a clear …

We report evidence from APOGEE for the presence of a new metal-poor stellar structure
located within∼ 4 kpc of the Galactic Centre. Characterized by a chemical composition …

Context. The nuclear stellar disc (NSD) is, together with the nuclear star cluster (NSC) and
the central massive black hole, one of the main components in the central parts of our Milky …

Using modern isochrones with customized physics and carefully considered statistical
techniques, we recompute the age distribution for a sample of 91 microlensed dwarfs in the …

We compare abundance ratio trends in a sample of∼ 11,000 Milky Way bulge stars (R GC<
3 kpc) from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) to those …

We present photometric metallicity measurements for a sample of 2.6 million bulge red
clump stars extracted from the Blanco DECam Bulge Survey (BDBS). Similar to previous …
