The GALAH Survey: Neutron-Capture Elemental Abundances for 350,000 Gaia-RVS spectra and the Chemodynamics of Accreted Structures
Pradosh Barun Das, Daniel B. Zucker, Aldo Mura-Guzmán +15
We present a comprehensive data-driven spectroscopic analysis of 357,415 red giant stars using Gaia DR3 Radial Velocity Spectrometer (RVS) spectra (8460-8700 A; ),…
Dawn of the Milky Way disk: Determination of when a rotationally supported disk appears and dating the spin-up of the disk
Sofia Feltzing, Diane Feuillet, Thomas Bensby
Spiral galaxies, like the Milky Way, transform at some point in time into a rotationally supported system. Using an extant data-set consisting of 319 835 sub-giants from LAMOST wit…
Searching for and characterizing halo substructures with the GALAH DR4 survey
Iryna Kushniruk, Kristopher Youakim, Karin Lind +12
Recent studies show that the Milky Way stellar halo is composed of populations of different origins, shaped by multiple accretion events. To better understand the formation of the…
That's so Retro: The Gaia-Sausage-Enceladus Merger Trajectory as the Origin of the Chemical Abundance Bimodality in the Milky Way Disk
James W. Johnson, Diane K. Feuillet, Ana Bonaca +1
The Milky Way (MW) is thought to have experienced a 3:1 mass-ratio merger event near redshift with a significantly retrograde trajectory. This now-disrupted dwarf ga…
First large scale spatial and velocity patterns of local metal-rich stars in the Milky Way
Georges Kordopatis, Diane Feuillet, Christian Lehmann +4
(Abridged) The present-day spatial and kinematic distribution of stars in the Milky Way provides key constraints on its internal dynamics and evolutionary history. We select stars…
Disentangling Milky Way halo populations at low metallicities using [Al/Fe]
H. Ernandes, Á. Skúladóttir, S. Feltzing +1
Differentiating between in-situ and accreted populations in the Milky Way halo is a challenging task. Various kinematic spaces are often used to identify distinct accreted populati…
Evidence of Gaia Enceladus experiencing at least two passages around the Milky Way
Ása Skúladóttir, Heitor Ernandes, Diane K. Feuillet +4
One of the major recent breakthroughs has been the discovery of the last Major Merger to happen in the history of the Milky Way. Around 10 Gyr ago the galaxy Gaia Enceladus, with e…
Gaia-Sausage-Enceladus star formation history as revealed by detailed elemental abundances
H. Ernandes, D. Feuillet, S. Feltzing +1
The Gaia-Sausage-Enceladus was the last major merger and central turning point in the Milky Way's story. This event, comparable in mass to the Large Magellanic Cloud today, left be…
Gaia-Sausage-Enceladus star formation history as revealed by detailed elemental abundances
H. Ernandes, D. Feuillet, S. Feltzing +1
The Gaia-Sausage-Enceladus merger was a major event in the history of the Milky Way. Studies on Milky Way satellite dwarf galaxies show that key elemental abundance patterns, which…
