Metal-Poor Gas Accretion Drives Giant Clump Formation at 0.6 < z < 2.6
Visal Sok, Adam Muzzin, Ben Forrest +20
The physical properties of kiloparsec-scale clumps in high-redshift star-forming galaxies (SFGs) contain crucial constraints on how they assemble. Building on recent work that indi…
Towards Unbreaking the Universe: MINERVA Measurements of Color Gradients in Massive Quiescent Galaxies Can Help Ease Too-Early Star Formation Tensions
Sam E. Cutler, Luke Robbins, Danilo Marchesini +41
The discovery of a population of massive, ancient quiescent galaxies within the first 2 Gyr of the Universe's history has led to significant tensions with models of galaxy formatio…
RUBIES: The Evolution of the Ionization Parameter from 0 < z < 9
Nikko J. Cleri, Zach J. Lewis, Joel Leja +10
The dimensionless ionization parameter, U=q/c, where q is the ratio of the local ionizing photon flux to the local hydrogen density, is a key metric to parameterize nebular conditi…
MAGAZ3NE: Spatially Resolved Ages and Chemical Abundances of Ultra-Massive Quiescent Galaxies at z 3.5 using JWST/NIRSpec IFU
Adit H. Edward, Jacqueline Antwi-Danso, Adam Muzzin +14
We present spatially-resolved measurements of stellar age, [Fe/H], and [/Fe] in three ultra-massive (), compact ( kpc) qui…
The Missing Hard Photons of Little Red Dots: Their Incident Ionizing Spectra Resemble Massive Stars
Bingjie Wang, Joel Leja, Harley Katz +11
The nature of Little Red Dots (LRDs) has largely been investigated through their continuum emission, with lines assumed to arise from a broad-line region. In this paper, we instead…
A massive and evolved slow-rotating galaxy in the early Universe
Ben Forrest, Adam Muzzin, Danilo Marchesini +15
In the contemporary Universe, most galaxies are supported by ordered rotation, yet a significant subset of the most massive and quiescent systems are dominated by random stellar mo…
