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…
An (in)complete NIRSpec census of Balmer absorption in Type 1 AGN -- radiation-driven outflows in little red dots, quasars and variable stars
Ignas Juodžbalis, Xihan Ji, Francesco D'Eugenio +17
A notable achievement of the first generation of JWST surveys was the discovery of an abundance of faint high-redshift () broad-line active galactic nuclei (AGN) in the $L_{…
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…
From filaments to clumps: filament properties with synthetic Herschel observations
Zhen-Xing Ma, Zu-Jia Lu
Systematic surveys of filaments have been conducted to study their properties and their relationship to the process of star formation. In this paper, we use synthetic Herschel obse…
The Way We Tally Becomes the Tale: the Impact of Selection Strategies on the Inferred Evolution of Little Red Dots Across Cosmic Time
Pierluigi Rinaldi, Kevin Hainline, Francesco D'Eugenio +27
Little Red Dots (LRDs) have emerged as a key population linked to early black hole growth, yet photometric selections have predominantly targeted only the most extreme red systems,…
