SSSpaNG! Stellar Spectra as Sparse, data-driven, Non-Gaussian processes
Stephen M. Feeney, Benjamin D. Wandelt, Melissa K. Ness
Upcoming million-star spectroscopic surveys have the potential to revolutionize our view of the formation and chemical evolution of the Milky Way. Realizing this potential requires…
Chemodynamics of barred galaxies in cosmological simulations: On the Milky Way's quiescent merger history and in-situ bulge
F. Fragkoudi, R. J. J. Grand, R. Pakmor +9
We explore the chemodynamical properties of a sample of barred galaxies in the Auriga magneto-hydrodynamical cosmological zoom-in simulations, which form boxy/peanut (b/p) bulges,…
Discovery of s-process enhanced stars in the LAMOST survey
Brodie J Norfolk, Andrew R Casey, Amanda I Karakas +7
Here we present the discovery of 895 s-process-rich candidates from 454,180 giant stars observed by the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) using a d…
The Inside-out Growth of the Galactic Disk
Neige Frankel, Jason Sanders, Hans-Walter Rix +2
We quantify the inside-out growth of the Milky Way's low-alpha stellar disk, modelling the ages, metallicities and Galactocentric radii of APOGEE red clump stars with 6 < R < 13 kp…
In Pursuit of Galactic Archaeology: Astro2020 Science White Paper
Melissa Ness, Jonathan Bird, Jennifer Johnson +30
The next decade affords tremendous opportunity to achieve the goals of Galactic archaeology. That is, to reconstruct the evolutionary narrative of the Milky Way, based on the empir…
Variations in -element ratios trace the chemical evolution of the disk
Kirsten Blancato, Melissa Ness, Kathryn V. Johnston +2
It is well established that the chemical structure of the Milky Way exhibits a bimodality with respect to the -enhancement of stars at a given [Fe/H]. This has been studied larg…
