PhotoIFU: NIRCam as a Photometric Integral Field Unit for Mapping Feedback in Galaxies
Yongda Zhu, Marcia J. Rieke, Courtney Carreira +25
We present PhotoIFU, a workflow that uses deep multi-band imaging as a low-resolution photometric integral field unit. Applied to PSF-matched JWST/NIRCam imaging, PhotoIFU treats e…
A quasar hatching from a buried red phase at z = 3.7
Zheng Ma, Yongda Zhu, Zhiyuan Ji +21
We present JADES-GS 209777, previously cataloged as CANDELS J033238.02-274626.2, hereafter "the Hatchling," a red quasar at . While the source has been reported in earlier…
The JADES Transient Survey III: Linking Core-Collapse Supernova Rates to Cosmic Star Formation
Christian Vassallo, Seppo Mattila, Christa DeCoursey +24
The paper uses JWST JADES transient survey data to compare core‑collapse supernova rates with cosmic star‑formation rate densities from redshift 0 to 5, exploring the impact of the…
The JADES Transient Survey II: Volumetric Supernova Rates out to z~5
Christa DeCoursey, Christian Vassallo, Louis-Gregory Strolger +27
The paper uses JWST/NIRCam observations from the JADES Transient Survey to measure the first volumetric rates of core‑collapse and Type Ia supernovae at redshifts 2–5, employing ph…
A Pixel-by-Pixel Path to Population III Discovery with JWST
Patricia Iglesias-Navarro, Thomas Harvey, Marc Huertas-Company +11
The identification of the first generation of metal-free stars, known as Population III (Pop~III), remains a primary goal of modern observational astronomy. While JWST has discover…
Early metal-enriched baryon cycling before the midpoint of cosmic reionization
Yongda Zhu, Zhiyuan Ji, George D. Becker +13
Models predict that chemical enrichment and gas redistribution should begin rapidly once star formation starts, but direct constraints at the earliest epochs have been scarce. Here…
