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…
Optical observations of candidate host galaxies of eight fast X-ray transients
Agnes P. C. van Hoof, Peter G. Jonker, Lieke Tommel +15
Fast X-ray transients (FXTs) are extragalactic flashes of X-rays with a typical duration of minutes to hours for which a variety of origins has been proposed and observed. To decip…
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…
Probing Direct Contributions of Galaxies and AGN to Cosmic Reionization in a Quasar Field J0226+0302 with JWST NIRCam and NIRSpec
Xiangyu Jin, Jinyi Yang, Feige Wang +19
We present JWST Cycle 2 NIRCam and NIRSpec observations in a quasar field J0226+0302 at z=6.5412 to probe the direct connections between the intergalactic medium (IGM), galaxies, a…
High-Resolution ALMA Imaging for a Gravitationally-lensed Quasar at : Constraining the AGN Contribution to Galactic-Scale Dust Heating
Minghao Yue, Xiaohui Fan, Anna-Christina Eilers +6
We present high-resolution (beam size $0\farcs076\times0\farcs040$) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the far-infrared $(λ_\text{rest}=162.7μ\rm…
Quantifying biases in stellar masses of JWST high-z quasar host galaxies caused by quasar subtraction
Sabrina Berger, Madeline A. Marshall, J. Stuart B. Wyithe +4
JWST has enabled dozens of high- quasar host galaxy detections. Many of these observations imply galaxies with black holes that are overmassive compared to their low- counter…
