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…

The Way We Tally Becomes the Tale: the Impact of Selection Strategies on the Inferred Evolution of Little Red Dots Across Cosmic Time

Pierluigi Rinaldi, Kevin Hainline, Francesco D'Eugenio +27

Little Red Dots (LRDs) have emerged as a key population linked to early black hole growth, yet photometric selections have predominantly targeted only the most extreme red systems,…

Calibrating Photometric Mid-Infrared Star Formation Rates for JWST

Stacey Alberts, George H. Rieke, Irene Shivaei +13

The mid-infrared (IR) spectrum of galaxies has a long history as a valuable proxy for the dust-obscured star formation rate (SFR) in massive galaxies. Now, with JWST, we can explor…

Filling the Gap in Cluster Evolution: JWST's Glimpse into a Young, Star-Forming Cluster at Cosmic Noon

Pierluigi Rinaldi, Stacey Alberts, Christopher N. A. Willmer +12

We present a detailed study of HUDFJ0332.4-2746.6 (HUDF46), a overdensity in the Hubble Ultra Deep Field, previously identified with HST as a proto-cluster. JWST/N…

The Little Blue and Red Dots Rosetta Stones: Non-Gaussian broad lines, hot dust, and X-ray weakness

M. Brazzini, F. D'Eugenio, R. Maiolino +31

The population of Active Galactic Nuclei (AGN) newly discovered by the James Webb Space Telescope (JWST) exhibits peculiar properties that distinguish it from both local type I AGN…

Not Just a Dot: the complex UV morphology and underlying properties of Little Red Dots

P. Rinaldi, N. Bonaventura, G. H. Rieke +31

We analyze 99 photometrically selected Little Red Dots (LRDs) at in the GOODS fields, leveraging ultra-deep JADES NIRCam short-wavelength (SW) data. We examine the…
