Bright Galaxies at Cosmic Dawn: A Cloud-Scale Star Formation Model Unifying Variable SFE, IMFs, and Stochasticity
Elie Cueto, Anne Hutter
To investigate the origins of the high abundance of UV-bright galaxies at z > 10, we present a new semi-analytic model that bridges the gap between small-scale star formation physi…
Exploring Cosmic Dawn with PANORAMIC II: Cosmic Variance and Galaxy Clustering at
Andrea Weibel, Christian Kragh Jespersen, Pascal A. Oesch +10
Observational campaigns with JWST have revealed a higher-than-expected abundance of UV-bright galaxies at , with various proposed theoretical explanations. A powerful c…
PANORAMIC: Discovery of an Ultra-Massive Grand-Design Spiral Galaxy at
Mengyuan Xiao, Christina C. Williams, Pascal A. Oesch +26
We report the discovery of an ultra-massive grand-design red spiral galaxy, named Zhúlóng (Torch Dragon), at in the JWST PANORAMIC survey, iden…
Astraeus X: Indications of a top-heavy initial mass function in highly star-forming galaxies from JWST observations at z>10
Anne Hutter, Elie R Cueto, Pratika Dayal +3
The James Webb Space Telescope (JWST) has uncovered an abundance of galaxies bright in the ultraviolet (UV) that has challenged traditional theoretical models at high redshi…
Mapping reionization bubbles in the JWST era I: empirical edge detection with Lyman alpha emission from galaxies
Ting-Yi Lu, Charlotte A. Mason, Andrei Mesinger +7
Ionized bubble sizes during reionization trace physical properties of the first galaxies. JWST's ability to spectroscopically confirm and measure Lyman-alpha (Ly) emission in s…
The PANORAMIC Survey: Pure Parallel Wide Area Legacy Imaging with JWST/NIRCam
Christina C. Williams, Pascal A. Oesch, Andrea Weibel +15
We present the PANORAMIC survey, a pure parallel extragalactic imaging program with NIRCam observed during JWST Cycle 1. The survey obtained 530 sq arcmin of NIRCam imaging f…
