Where Galaxies Go to Die: The Environments of Massive Quiescent Galaxies at
Ian McConachie, Anna de Graaff, Michael V. Maseda +25
At low redshift, massive quiescent galaxies (MQGs) are most frequently found in massive, rich galaxy clusters, but at high redshift the trend is less clear. Here, we present spectr…
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…

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…
Unusually High Gas-to-Dust Ratios Observed in High-Redshift Quiescent Galaxies
Justin S. Spilker, Katherine E. Whitaker, Desika Narayanan +15
Tracking the cold molecular gas contents of galaxies is critical to understand the interplay between star formation and galaxy growth across cosmic time. Observations of the long-w…
Exploring Cosmic Dawn with PANORAMIC I: The Bright End of the UVLF at
Andrea Weibel, Pascal A. Oesch, Christina C. Williams +14
In its first two years of operation, the James Webb Space Telescope has enabled the discovery of a surprising number of UV-bright galaxies at . Their number density is…
RUBIES: A Spectroscopic Census of Little Red Dots; All V-Shaped Point Sources Have Broad Lines
Raphael E. Hviding, Anna de Graaff, Tim B. Miller +16
The physical nature of Little Red Dots (LRDs) - a population of compact, red galaxies revealed by JWST - remains unclear. Photometric samples are constructed from varying selection…
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…
Population Models for Star Formation Timescales in Early Galaxies: The First Step Towards Solving Outshining in Star Formation History Inference
Bingjie Wang, Joel Leja, Hakim Atek +13
JWST have revealed temporarily-quenched and ultraviolet-luminous galaxies in the early universe, suggesting enhanced star formation stochasticity. Verifying this hypothesis is crit…
