A value-added catalogue of neural network-based europium abundances for GALAH DR4

Sarah G. Kane, Zofia Kaczmarek, Andrew Garner +3

The rapid neutron-capture (-process) element europium (Eu) is a valuable tracer of neutron star mergers and other rare nucleosynthetic events. The stellar spectroscopic survey G…

Trading oxygen for iron II. Oxygen- versus iron-dependent cosmic star formation history

Martyna Chruślińska, Mirko Curti, Ruediger Pakmor +4

Due to their different nucleosynthetic origin, a stellar population produces oxygen (O) and iron (Fe) on different timescales and their relative abundance can deviate strongly from…

The R-Process Alliance: Exploring the cosmic scatter among ten r-process sites with stellar abundances

Mila Racca, Terese T. Hansen, Ian U. Roederer +11

The astrophysical origin of the rapid neutron-capture process (r-process), which produces about half of the elements heavier than iron, remains uncertain. The oldest, most metal-po…

The chemodynamical memory of a major merger in a NIHAO-UHD Milky Way analogue -- II. Were Splash stars heated or already born hot?

Sven Buder, Tobias Buck, Ása Skúladóttir +3

One of the most debated consequences of the Milky Way's last major merger is the so-called : stars with disc-like chemistry but halo-like kinematics, often interpreted as e…

The chemodynamical memory of a major merger in a NIHAO-UHD Milky Way analogue -- I. A golden thread through time and space

Sven Buder, Tobias Buck, Ása Skúladóttir +3

Understanding how past major mergers shaped the Milky Way's present-day structure is a key goal of Galactic archaeology. The Galaxy's chemical and dynamical structure retains the i…

On the connection between nitrogen-enhanced field stars and the Galactic globular clusters

Sarah G. Kane, Vasily Belokurov, Stephanie Monty +6

As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the M…

JADES: the chemical enrichment pattern of distant galaxies -- enhancement, silicon depletion, and iron enhancement

Yuki Isobe, Roberto Maiolino, Xihan Ji +26

We present gas-phase abundances of carbon (C), -elements (O, Ne, Si, and Ar) and iron (Fe) obtained from stacked spectra of high- star-forming galaxies with the deep Near Inf…

A direct black hole mass measurement in a Little Red Dot at the Epoch of Reionization

Ignas Juodžbalis, Cosimo Marconcini, Francesco D'Eugenio +37

Recent discoveries of faint active galactic nuclei (AGN) at the redshift frontier have revealed a plethora of broad \Halpha emitters with optically red continua, named Little Red D…

ChemZz I: Comparing Oxygen and Iron Abundance Patterns in the Milky Way, the Local Group and Cosmic Noon

Stephanie Monty, Allison L. Strom, Thomas M. Stanton +7

Our understanding of the chemical evolution of galaxies has advanced through measurements from both distant galaxies across redshift, and our own Milky Way (MW). To form a comprehe…

The THESAN-ZOOM project: Mystery N/O more -- uncovering the origin of peculiar chemical abundances and a not-so-fundamental metallicity relation at

William McClymont, Sandro Tacchella, Aaron Smith +15

We present an analysis of metallicities and chemical abundances at in the THESAN-ZOOM simulations. We find that smoothly curved gas-phase and stellar mass-metallicity rela…

Connecting JWST discovered N/O-enhanced galaxies to globular clusters: Evidence from chemical imprints

Xihan Ji, Vasily Belokurov, Roberto Maiolino +5

Recent JWST observations have revealed a growing population of galaxies at with elevated nitrogen-to-oxygen ratios. These "N/O-enhanced" galaxies (NOEGs) exhibit near- to sup…
