Evolution of the Mass–Metallicity Relation from Redshift z ≈ 8 to the Local Universe
The Astrophysical Journal, 2023 A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of this correlation can strongly constrain theories of galaxy evolution.

A 30m Large Program: The CO Line Atlas of the Whirlpool Galaxy Survey (CLAWS) [PDF]
EPJ Web of Conferences, 2022 Robust knowledge of the distribution, amount, and physical/chemical state of the cold molecular (H2) gas is key to understanding galaxy evolution. With the help of multi-CO line observations, it is possible to study the molecular gas distribution and ...

THE NEW MODEL OF CHEMICAL EVOLUTION OF r-PROCESS ELEMENTS BASED ON THE HIERARCHICAL GALAXY FORMATION. I. Ba AND Eu [PDF]
, 2014 We investigate the chemical enrichment of r-process elements in the early evolutionary stages of the Milky Way halo within the framework of hierarchical galaxy formation using a semi-analytic merger tree.

The Origin of the Nuclear Star-forming Ring in NGC 3182
The Astronomical Journal, 2023 We investigate the stellar and ionized gas kinematics, and stellar populations of NGC 3182 galaxy using integral field spectrograph data from the Calar Alto Legacy Integral Field Area survey. We try to clarify the nature of the ring structure in NGC 3182.

Radial migration in a bar-dominated disk galaxy I: Impact on chemical evolution [PDF]
, 2013 We study radial migration and chemical evolution in a bar-dominated disk galaxy, by analyzing the results of a fully self-consistent, high resolution N-body+SPH simulation. We find different behaviours for gas and star particles. Gas within corotation is

De re metallica: the cosmic chemical evolution of galaxies [PDF]
The Astronomy and Astrophysics Review, 2018 The evolution of the content of heavy elements in galaxies, the relative chemical abundances, their spatial distribution, and how these scale with various galactic properties, provide unique information on the galactic evolutionary processes across the ...

THE COMPARATIVE CHEMICAL EVOLUTION OF AN ISOLATED DWARF GALAXY: A VLT AND KECK SPECTROSCOPIC SURVEY OF WLM [PDF]
, 2013 Building on our previous spectroscopic and photometric analysis of the isolated Local Group dwarf irregular (dIrr) galaxy WLM, we present a comparison of the metallicities of its red giant branch stars with respect to the well-studied Local Group dwarf ...

Galaxy formation with radiative and chemical feedback [PDF]
, 2015 Here we introduce GAMESH, a novel pipeline which implements self-consistent radiative and chemical feedback in a computational model of galaxy formation. By combining the cosmological chemical-evolution model GAMETE with the radiative transfer code CRASH,

Resolved Multi-element Stellar Chemical Abundances in the Brightest Quiescent Galaxy at z ∼ 2 [PDF]
Astrophysical Journal, 2020 Measuring the chemical composition of galaxies is crucial to our understanding of galaxy formation and evolution models. However, such measurements are extremely challenging for quiescent galaxies at high redshifts, which have faint stellar continua and ...
