Streams, substructures, and the early history of the Milky Way
A Helmi - Annual Review of Astronomy and Astrophysics, 2020 - annualreviews.org
The advent of the second data release of the Gaia mission, in combination with data from
large spectroscopic surveys, is revolutionizing our understanding of the Galaxy. Thanks to …

Chemodynamical history of the galactic bulge
The Galactic Bulge can uniquely be studied from large samples of individual stars and is
therefore of prime importance for understanding the stellar population structure of bulges in …

From dawn till disc: Milky Way's turbulent youth revealed by the APOGEE+Gaia data
We use accurate estimates of aluminium abundance from the APOGEE Data Release 17
and Gaia Early Data Release 3 astrometry to select a highly pure sample of stars with …

Tracing galaxy formation with stellar halos. I. Methods
If the favored hierarchical cosmological model is correct, then the Milky Way system should
have accreted~ 100-200 luminous satellite galaxies in the past~ 12 Gyr. We model this …

The origin of accreted stellar halo populations in the Milky Way using APOGEE, Gaia, and the EAGLE simulations
Recent work indicates that the nearby Galactic halo is dominated by the debris from a major
accretion event. We confirm that result from an analysis of APOGEE-DR14 element …

Elemental abundance survey of the Galactic thick disc
BE Reddy, DL Lambert, CA Prieto - Monthly Notices of the Royal …, 2006 - academic.oup.com
We have performed an abundance analysis for F-and G-dwarfs of the Galactic thick-disc
component. A sample of 176 nearby (d≤ 150 pc) thick-disc candidate stars was chosen …

Uncovering the birth of the Milky Way through accurate stellar ages with Gaia
Abstract Knowledge of the ages of the stars formed over a galaxy's lifetime is fundamental to
an understanding of its formation and evolution. However, stellar ages are difficult to obtain …

The age structure of stellar populations in the solar vicinity-Clues of a two-phase formation history of the Milky Way disk
M Haywood, P Di Matteo, MD Lehnert, D Katz… - Astronomy & …, 2013 - aanda.org
We analyze a sample of solar neighborhood stars that have high-quality abundance
determinations and show that there are two distinct regimes of [α/Fe] versus age, which we …
