The Astrophysical JournalThe observed chemical diversity of Milky Way stars places important constraints on Galactic chemical evolution and the mixing processes that operate within the interstellar medium. Recent works have found that the chemical diversity of disk stars is low.

The chemical evolution of elliptical galaxies
The Astrophysical Journal, 1980 U--R colors of elliptical and SO galaxies have been synthesized by combining the stellar populations of galactic globular clusters in accordance with a simple mass-loss chemical evolutionary model. We can account in a satisfactory way for the range, shape, and dispersion of the color-magnitude relation observed by Sandage and Visvanathan.

The Astrophysical JournalUsing more than 100 galaxies in the MUSE Ultra Deep Field with spectroscopy from the Hubble Space Telescope’s (HST) Wide Field Camera 3 and the Very Large Telescope’s Multi Unit Spectroscopic Explorer, we extend the gas-phase mass–metallicity relation ...

AEOS: Star-by-star Cosmological Simulations of Early Chemical Enrichment and Galaxy Formation
The Astrophysical JournalThe A eos project introduces a series of high-resolution cosmological simulations that model star-by-star chemical enrichment and galaxy formation in the early Universe, achieving 1 pc resolution.

An Analytical Galactic Chemical Evolution Model with Gas Inflow and a Terminal Wind
The Astrophysical JournalWe present a new analytical galactic chemical evolution (GCE) model with gas inflow, internally caused outflow, and extra gas loss after a period of time. The latter mimics the ram pressure stripping of a dwarf satellite galaxy near the pericenter of its

On the Evolutionary History of a Simulated Disk Galaxy as Seen by Phylogenetic Trees
The Astrophysical JournalPhylogenetic methods have long been used in biology and more recently have been extended to other fields—for example, linguistics and technology—to study evolutionary histories.

Quantifying Bursty Star Formation in Dwarf Galaxies
The Open Journal of AstrophysicsDwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than ~100 Myr should lead to discontinuous
