Ripples of Stellar Enrichment (RoSE) -- simulating element production and mixing in the Milky Way star-by-star
Chuhan Zhang, Mark R. Krumholz, Melissa K. Ness +3
We present the Ripples of Stellar Enrichment (RoSE) simulations, which follow a Milky Way-like isolated disc galaxy with star-by-star feedback and nucleosynthesis from all signific…
How Mergers and Flybys Shape Azimuthal Age Patterns in Spiral Galaxies
Qian-Hui Chen, Alex M. Garcia, Zefeng Li +7
Spiral structures are one of the most common features in galaxies, yet their origins and evolution remain debated. Stellar age distributions offer crucial insights into galaxy evol…
Metallicity fluctuation statistics in the interstellar medium and young stars -- II. Elemental cross-correlations and the structure of chemical abundance space
Mark R. Krumholz, Yuan-Sen Ting, Zefeng Li +3
Observations of Milky Way stars by multiplexed spectroscopic instruments and of gas in nearby galaxies using integral field units have made it possible to measure the abundances of…
Element nucleosynthetic origins from abundance spatial distributions beyond the Milky Way
Zefeng Li, Mark R. Krumholz, Anna F. McLeod +7
An element's astrophysical origin should be reflected in the spatial distribution of its abundance, yielding measurably different spatial distributions for elements with different…
Understanding the Mechanisms Behind the Distribution of Galactic Metals
Chuhan Zhang, Zefeng Li, Zipeng Hu +1
The evolution and distribution of metals within galaxies are critical for understanding galactic evolution and star formation processes, but the mechanisms responsible for shaping…
Comparing metallicity correlations in nearby non-AGN and AGN-host galaxies
Song-lin Li, Zefeng Li, Emily Wisnioski +2
The gas-phase metallicity distribution within galaxies records critical information about galactic evolution. In this work we investigate how active galactic nuclei (AGN) influence…
