To be lensed or not to be lensed: on the nature of the alleged high-z lensed quasars J0109-5424 and P170+20
Aurora Mata-Sanchez, Emanuele P. Farina, Anniek J. Gloudemans +17
We present a detailed multi-wavelength analysis of two gravitationally lensed z>6 quasar candidates: J0109-5424 and P170+20. Using JWST/NIRSpec near-infrared data from the Aether s…
Quasar Impostors: Two Extremely UV-Bright () Reionisation-Epoch Galaxies Powered by Very Massive Stars
Daming Yang, Joseph F. Hennawi, Sarah E. I. Bosman +20
The extreme bright end of the galaxy UV luminosity function during reionisation remains poorly constrained, particularly where the galaxy and quasar luminosity functions overlap an…
NEXUS: Spectral Variability of Little Red Dots and Blue Active Galactic Nuclei at
Zachary Stone, Yue Shen, Ming-Yang Zhuang +4
We present spectral measurements for 17 Little Red Dots (LRDs) and 14 blue broad-line active galactic nuclei (AGNs) at using multi-epoch JWST NIRSpec MSA s…
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…
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{m…
