Discovery of red galaxy candidates at z ~ 12: Early dust growth or significant nebular emission with high-temperature stars?
Ikki Mitsuhashi, Katherine A. Suess, Joel Leja +18
We report the discovery of two z ~ 12 galaxy candidates with unusually red UV slopes (betaUV ~> -1.5), and probe the origin of such colors at cosmic dawn. From Prospector fits to t…
What you see is what you get: empirically measured bolometric luminosities of Little Red Dots
Jenny E. Greene, David J. Setton, Lukas J. Furtak +27
New populations of red active galactic nuclei (known as ``Little Red Dots'') discovered by JWST exhibit remarkable spectral energy distributions. Leveraging X-ray through far-infra…
RUBIES spectroscopically confirms the high number density of quiescent galaxies from
Yunchong Zhang, Anna de Graaff, David J. Setton +21
We present the number density of massive () quiescent galaxies at using JWST NIRSpec PRISM spectra. This work relies on spectra fr…
MINERVA: A NIRCam Medium Band and MIRI Imaging Survey to Unlock the Hidden Gems of the Distant Universe
Adam Muzzin, Katherine A. Suess, Danilo Marchesini +81
We present an overview of the MINERVA survey, a 259.8 hour (prime) and 127 hour (parallel) Cycle 4 treasury program on the James Webb Space Telescope (JWST). MINERVA is obtaining 8…
JWST+ALMA reveal the build up of stellar mass in the cores of dusty star-forming galaxies at Cosmic Noon
Sarah Bodansky, Katherine E. Whitaker, Ayesha Abdullah +14
Dusty star-forming galaxies have long been suspected to serve as the missing evolutionary bridge between the star-forming and quiescent phases of massive galaxy evolution. With the…
Taking a Break at Cosmic Noon: Continuum-selected Low-mass Galaxies Require Long Burst Cycles
Abby Mintz, David J. Setton, Jenny E. Greene +25
While bursty star formation in low-mass galaxies has been observed in local populations and reproduced in simulations, the dormant phase of the burst cycle has not been well studie…
Measuring Emission Lines with JWST-MegaScience Medium-Bands: A New Window into Dust and Star Formation at Cosmic Noon
Brian Lorenz, Katherine A. Suess, Mariska Kriek +23
We demonstrate the power of JWST-NIRCam medium-band photometry to measure emission line fluxes and study dust and star formation properties of galaxies at cosmic noon. In this work…
The Structure and Formation Histories of Low-Mass Quiescent Galaxies in the Abell 2744 Cluster Environment
Sam E. Cutler, John R. Weaver, Katherine E. Whitaker +21
Low-mass quiescent galaxies are thought to predominantly reside in overdense regions, as environmental effects are often invoked to explain their shutdown of star formation. These…
A confirmed deficit of hot and cold dust emission in the most luminous Little Red Dots
David J. Setton, Jenny E. Greene, Justin S. Spilker +33
Luminous broad H emission and red rest-optical SEDs are the hallmark of compact Little Red Dots (LRDs), implying highly attenuated dusty starbursts and/or obscured active galact…
Investigating photometric and spectroscopic variability in the multiply-imaged Little Red Dot A2744-QSO1
Lukas J. Furtak, Amy R. Secunda, Jenny E. Greene +25
JWST observations have uncovered a new population of red, compact objects at high redshifts dubbed `Little Red Dots' (LRDs), which typically show broad emission lines and are thoug…
The Evolution of Half-Mass Radii and Color Gradients for Young and Old Quiescent Galaxies at with JWST/PRIMER
Maike Clausen, Ivelina Momcheva, Katherine E. Whitaker +12
We present a study of the size growth of the red sequence between tracing the evolution of quiescent galaxies in both effective half-light and half-mass radii using mult…
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…
