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…
Anatomy of an ionized bubble: NIRCam grism spectroscopy of the double-peaked Lyman- emitter COLA1 and its environment
Alberto Torralba-Torregrosa, Jorryt Matthee, Rohan P. Naidu +10
The increasingly neutral intergalactic gas at impacts the Lyman- flux observed from galaxies. One luminous galaxy, COLA1, stands out because of its unique double-peaked L…
