Rising from the Ashes II: The Bar-driven Abundance Bimodality of the Milky Way
Angus Beane, James Johnson, Vadim Semenov +3
The Milky Way hosts at least two modes in its present day distribution of Fe and alpha-elements. The exact cause of this bimodality is disputed, but one class of explanations invol…
From UV-bright Galaxies to Early Disks: the Importance of Turbulent Star Formation in the Early Universe
Vadim A. Semenov, Charlie Conroy, Lars Hernquist
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 galacti…
How Early Could the Milky Way's Disk Form?
Vadim A. Semenov, Charlie Conroy, Aaron Smith +2
We investigate early, , galaxy formation in a cosmological zoom-in simulation of a close, early-forming Milky Way (MW) analog extracted from TNG50 simulation and resimulated…
Cosmological Simulations of Stellar Halos with Gaia Sausage-Enceladus Analogues: Two Sausages, One Bun?
Dylan Folsom, Mariangela Lisanti, Lina Necib +3
Observations of the Milky Way's stellar halo find that it is predominantly comprised of a radially biased population of stars, dubbed the Gaia Sausage--Enceladus, or GSE. These sta…
On the Origin of High-velocity Clouds in the Galaxy
Scott Lucchini, Jiwon Jesse Han, Lars Hernquist +1
The origin of our Galaxy's high-velocity clouds (HVCs) remains a mystery after many decades of effort. In this paper, we use the TNG50 simulation of the IllustrisTNG project to ide…
