The Chemical Evolution of the Milky Way

, 1999
The field of chemical evolution modeling of the Galaxy is experiencing in the last years a phase of high activity and important achievements. There are, however, several open questions which still need to be answered. In this review I summarize what have

The MUSE Ultra Deep Field (MUDF). V. Characterizing the Mass–Metallicity Relation for Low-mass Galaxies at z ∼ 1–2

The Astrophysical Journal
Using 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 ...

THE LOCAL DWARF GALAXIES:BUILDING BLOCKS OFMASSIVE ONES? I.THE FORNAX DWARF GALAXY

Odessa Astronomical Publications, 2008
A chemical evolution of the Local Group dwarf galaxy Fornax is considered in the framework of the merger scenario. We suppose a galactic stellar halo to be formed as separate fragments which then merge; thus, we can calculate the set of such the ...

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.

An Analytical Galactic Chemical Evolution Model with Gas Inflow and a Terminal Wind

The Astrophysical Journal
We 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

Chemical Doppelgangers in GALAH DR3: The Distinguishing Power of Neutron-capture Elements among Milky Way Disk Stars

The Astrophysical Journal
The 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.

AEOS: Star-by-star Cosmological Simulations of Early Chemical Enrichment and Galaxy Formation

The Astrophysical Journal
The 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.

On the Evolutionary History of a Simulated Disk Galaxy as Seen by Phylogenetic Trees

The Astrophysical Journal
Phylogenetic 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.
