We present a novel method to constrain the formation time of the Milky Way disc using the
chrono-kinematic signatures of the inner Galaxy. We construct an O-rich Mira variable …

An advanced approach for definition of the" Milky Way galaxies-analogues"

IB Vavilova, PM Fedorov, DV Dobrycheva… - arxiv preprint arxiv …, 2024 - arxiv.org
Our Galaxy-the Milky Way-has certain features of the structure and evolution. The
morphological, photometric, kinematic, and chemodynamical properties are usually …

Effect of gas accretion on α-element bimodality in Milky Way-mass galaxies in the FIRE-2 simulations

H Parul, J Bailin, SR Loebman, A Wetzel… - Monthly Notices of …, 2025 - academic.oup.com
We analyse the stellar distributions on the [Fe/H]–[Mg/Fe] plane for 11 Milky Way-mass
galaxies from the FIRE-2 cosmological baryonic zoom-in simulations. Alpha-element …

Many elements matter: Detailed abundance patterns reveal star-formation and enrichment differences among Milky Way structural components

EJ Griffith, DW Hogg, S Hasselquist… - arxiv preprint arxiv …, 2024 - arxiv.org
Many nucleosynthetic channels create the elements, but two-parameter models
characterized by $\alpha $ and Fe nonetheless predict stellar abundances in the Galactic …

The chemical diversity of the metal-poor Milky Way

N Buckley, P Das, P Jofré, RM Yates… - Monthly Notices of the …, 2024 - academic.oup.com
We present a detailed study of the chemical diversity of the metal-poor Milky Way using data
from the GALAH DR3 survey. Considering 17 chemical abundances relative to iron ([X/Fe]) …

Blind source separation of the stellar halo

EY Davies, V Belokurov, A Kravtsov, S Monty… - arxiv preprint arxiv …, 2024 - arxiv.org
The stellar halo of the Milky Way comprises an abundance of chemical signatures from
accretion events and\textit {in-situ} evolution, that form an interweaving tapestry in kinematic …

From UV-bright Galaxies to Early Disks: the Importance of Turbulent Star Formation in the Early Universe

VA Semenov, C Conroy, L Hernquist - arxiv preprint arxiv:2410.09205, 2024 - arxiv.org
Bursty star formation at early times can explain the surprising abundance of early UV-bright
galaxies revealed by JWST but can also be a reason for the delayed formation of galactic …

Discovery of A Starburst in the Early Milky Way at [Fe/H]

B Chen, M Orkney, YS Ting, M Hayden - arxiv preprint arxiv:2501.14089, 2025 - arxiv.org
We present an analysis of very metal-poor (VMP) and metal-poor stars ($-3.0<\mathrm
{Fe/H]}<-1.5$) in the Gaia BP/RP or XP catalog, which reveals two distinct metallicity …
