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.

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 ...

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

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,

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 ...

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 Fall of a Giant. Chemical evolution of Enceladus, alias the Gaia Sausage [PDF]
, 2019 We present the first chemical evolution model for Enceladus, alias the Gaia Sausage, to investigate the star formation history of one of the most massive satellites accreted by the Milky Way during a major merger event.

Short-lived Radionuclides in the Milky Way Galaxy [PDF]
EPJ Web of Conferences, 2023 The short-lived radionuclides (SLRs) have a half-life ≤ 100 Myr. The γ-ray observations and excess abundance of their daughter nuclides in various meteoritic phases confirm the existence of SLRs in the Galaxy and early solar system (ESS), respectively ...
