Chemical hints of Population III stars from silicon abundances in massive galaxies
E. Eftekhari, A. Ferré-Mateu, A. Vazdekis +4
The formation of massive galaxies remains a fundamental question in astrophysics, with recent JWST observations suggesting that intense star formation occurred earlier than previou…
A stellar dynamical mass measurement of an inactive black hole at redshift 2
Andrew B. Newman, Meng Gu, Sirio Belli +34
Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…
The AURORA Survey: Multiple Balmer and Paschen Emission Lines for Individual Star-forming Galaxies at z=1.5-4.4. II. Implications for Nebular Dust Corrections, Nebular SFRs, and Differential Reddening
Naveen A. Reddy, Alice E. Shapley, Ryan L. Sanders +10
We discuss the implications of the nebular dust attenuation curves derived for 24 galaxies at z=1.5-4.4 with multiple detections of HI Balmer and Paschen recombination emission lin…
Clues to inside-out quenching in quiescent galaxies at : Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE
Chloe M. Cheng, Martje Slob, Mariska Kriek +16
[Abridged] Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into quenching and assembly mechanisms. Previous photometri…
Molecular Gas Excitation in z ~ 0.7 Gas-Rich Post-starburst Galaxies from SQuIGGLE
Vincenzo R. D'Onofrio, Justin S. Spilker, Rachel Bezanson +10
Many post-starburst galaxies at have been shown to retain substantial molecular gas reservoirs yet host low ongoing star formation, suggesting that the remaining gas may…
Are Nucleosynthetic Yields Universal? Interpreting the Multi-Elemental Abundances of Quiescent Galaxies over Cosmic Time Using Milky Way Stars
Aliza G. Beverage, David H. Weinberg, Mariska Kriek +3
The detailed abundance patterns of quiescent galaxies offer powerful constraints on their formation and evolution. Yet physical insight remains elusive, as nucleosynthetic yields a…
