Chemical evolution of the Milky Way disc with radial gas flows: a Lagrangian approach
Fiorenzo Vincenzo
Chemical abundance patterns result from the interplay between gas accretion, star formation, and radial mixing of gas and stars. Disentangling these processes is crucial to recover…
The influence of galaxy mergers, black-hole growth, and gas processes on the evolution of the stellar mass-gas metallicity relation of galaxies in different cosmic environments
Aaron R. Rowntree, Fiorenzo Vincenzo, Ankit Singh +3
We study the impact of supermassive black hole (SMBH) growth, , major and minor galaxy mergers, and gas processes, on the average gas metallic…
CLASSY XII: Nitrogen Enrichment Shaped by Gas Density and Feedback
Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +25
We investigate the chemical evolution of N/O using a sample of 45 local star-forming galaxies (SFGs) from the CLASSY survey. This sample spans a wide range of galaxy properties, wi…
The Role of Large-Scale Environment in Shaping the Stellar Mass-Gas Metallicity Relation Across Time
Aaron R. Rowntree, Fiorenzo Vincenzo, Ankit Singh +8
We study the stellar mass-gas metallicity relation (MZR) which shows a significant scatter for a fixed stellar mass. By defining global environments, nodes, filaments, and voids wi…
Constraining SN Ia Progenitors from the Observed Fe-peak Elemental Abundances in the Milky Way Dwarf Galaxy Satellites
Ryan K. Alexander, Fiorenzo Vincenzo
Chemical abundances of iron-peak elements in the red giants of ultra-faint dwarf galaxies (UFD) and dwarf spheroidal galaxies (dSph) are among the best diagnostics in the cosmos to…
The Environmental Dependence of the Stellar Mass - Gas Metallicity Relation in Horizon Run 5
Aaron R. Rowntree, Ankit Singh, Fiorenzo Vincenzo +11
Metallicity offers a unique window into the baryonic history of the cosmos, being instrumental in probing evolutionary processes in galaxies between different cosmic environments.…
CLASSY IX: The Chemical Evolution of the Ne, S, Cl, and Ar Elements
Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +20
To study the chemical evolution across cosmic epochs, we investigate Ne, S, Cl, and Ar abundance patterns in the COS Legacy Archive Spectroscopic SurveY (CLASSY). CLASSY comprises…
GTC Follow-up Observations of Very Metal-Poor Star Candidates from DESI
Carlos Allende Prieto, David S. Aguado, Jonay I. González Hernández +48
The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ~ 10, improving the…
Inhomogeneous Galactic Chemical Evolution: Modelling Ultra-Faint Dwarf Galaxies of the Large Magellanic Cloud
R. K. Alexander, F. Vincenzo, A. P. Ji +3
Ultra-faint dwarf galaxies are among the oldest and most metal-poor galaxies in the cosmos, observed to contain no gas and a high dark matter mass fraction. Understanding the chemi…
Chemical Evolution of Fluorine in the Milky Way
Kate A. Womack, Fiorenzo Vincenzo, Brad K. Gibson +5
Fluorine has many different potential sites and channels of production, making narrowing down a dominant site of fluorine production particularly challenging. In this work, we inve…
Empirical Constraints on the Nucleosynthesis of Nitrogen
James W. Johnson, David H. Weinberg, Fiorenzo Vincenzo +2
We derive empirical constraints on the nucleosynthetic yields of nitrogen by incorporating N enrichment into our previously developed and empirically tuned multi-zone galactic chem…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
Residual Abundances in GALAH DR3: Implications for Nucleosynthesis and Identification of Unique Stellar Populations
Emily J. Griffith, David H. Weinberg, Sven Buder +3
We investigate the [X/Mg] abundances of 16 elements for 82,910 Galactic disk stars from GALAH+ DR3. We fit the median trends of low-Ia and high-Ia populations with a two-process mo…
