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…
Toward 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…
How I Wonder What You Are -- JWST's Little Red Dots do not TWINKLE
Zhaoran Liu, Rohan P. Naidu, Amy Secunda +20
Little Red Dots (LRDs) are a population of compact, red sources that have emerged as one of the most puzzling findings of JWST. Variability provides a direct probe of their central…
Two Exciting High-redshift Galaxy Candidates Turn Out to Be Two Exciting Ultra-cool Brown Dwarfs
Maruša Bradač, Chris Willott, Yoshihisa Asada +37
From the onset of observations of JWST we have discovered unexpectedly luminous galaxies at redshifts and as high as . With their discovery, the question immediately f…
VENUS: Strong-lensing model of MACS J1931.8-2635 -- revealing the farthest multiply imaged supernova

We present a parametric strong-lensing model for the galaxy cluster MACS J1931.8-2635 (), accompanying the detection of the spectroscopically confirmed SN Eos at $z = 5…
A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13
David A. Coulter, Conor Larison, Justin D. R. Pierel +88
Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-r…

An Ancient Descendant of the First Galaxies
Jacqueline Antwi-Danso, Adam Muzzin, Luke Robbins +18
JWST has revealed unexpectedly bright galaxies in the first 500 Myr after the Big Bang. Their overabundance suggests that they are preferentially observed during burst phases, wher…
