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…

Winding Back the Clock: Recent Star Formation Histories of Massive Quiescent Galaxies Are Consistent With Their Rapid Number Density Evolution Since

Yunchong Zhang, Zhiyuan Ji, Rachel Bezanson +17

Massive quiescent galaxies have been identified out to in early JWST data in a substantial excess ( at ) of number densities from most theoretical…

PANORAMIC: The Dawn of Massive Quiescent Galaxies I. Number Density and Cosmic Variance from 1000 arcmin NIRCam Imaging

Zhiyuan Ji, Christina C. Williams, Peter Behroozi +13

We measure the number density and field-to-field variance of massive quiescent galaxies at - 8 using the JWST/NIRCam pure-parallel imaging survey PANORAMIC together with a…

Discovery of Ancient Globular Cluster Candidates in the Relic, a Quiescent Galaxy at

Katherine E. Whitaker, Sam E. Cutler, Rupali Chandar +31

Globular clusters (GCs) are some of the oldest bound structures in the Universe, holding clues to the earliest epochs of star formation and galaxy assembly. However, accurate age m…

A PANORAMIC of UV-optical morphologies of "Little Red Dots": Two groups of LRDs distinguished by UV half-light radius

Aidan P. Cloonan, Katherine E. Whitaker, Sinclaire M. Manning +13

Among the most remarkable results from JWST is the discovery of abundant, compact, and very red sources in the early Universe known as "Little Red Dots" (LRDs). The relative degree…

Everything Every Band All at Once II: The Relationship Between Optical Size and Stellar Mass Over Eight Billion Years of Cosmic History

Tim B. Miller, Yunchong Zhang, Sedona H. Price +24

While the size-mass relation provides insight into the structural evolution of galaxies, the data available and methods employed have hindered our ability to study a detailed and c…
