: a close quasar pair at cosmic dawn in the Aether survey
Silvia Onorato, Emanuele Paolo Farina, Roberto Decarli +32
We present the discovery and first characterization of : the most compact known quasar pair candidate in the Epoch of Reionization, with a projected se…
JWST/NIRSpec Reveals Diverse Nuclear Environments in Dwarf Galaxies Hosting AGN
Thomas Bohn, Archana Aravindan, Gabriela Canalizo +18
Dwarf galaxies, in the CDM framework, are expected to dominate the galaxy number density at all redshifts. As such, studying AGN in these systems, including characterizing their…
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…
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…
A 6.2 Quasar on the Local M- Relation Quenching Its Host Galaxy from the Aether Survey
Weizhe Liu, Emanuele Paolo Farina, Xiaohui Fan +19
We report JWST/NIRSpec integral field unit (IFU) observations of the quasar J15124422 at from the Aether survey. At 900 Myr after the Big Bang, this object al…
(LRDs): The Low-ReDshift Little Red Dots Survey. II. DESI DR1 Sample
Xiaojing Lin, Xiaohui Fan, Zheng Cai +12
JWST has revealed a substantial population of "Little Red Dots" (LRDs) at , challenging conventional AGN frameworks. However, the low-redshift regime remains largely unexplore…
Resolving the Multiphase Outflow, Shock Signatures, and PAHs in the AGN-Starburst Composite ULIRG F10565+2448 with JWST MIRI/MRS
Kylie Yui Dan, Jerome Seebeck, Sylvain Veilleux +9
We present new James Webb Space Telescope Mid-Infrared Instrument (MIRI) Medium-Resolution Spectrometer (MRS) observations of the nearby ultra-luminous infrared galaxy F10565+2448.…
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…
JWST Discovery of High-Velocity Mid-Infrared Ionized Outflows in Ultraluminous Infrared Galaxies F11119+3257 and F05189-2524
Jerome Seebeck, Kylie Yui Dan, Sylvain Veilleux +9
Ultra-fast outflows (UFOs) are thought to be a driving mechanism of large-scale winds driven by active galactic nuclei, which cause significant galactic feedback through quenching…
ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization
Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42
We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…
Shedding the envelope: JWST reveals a kiloparsec-scale [OIII]-weak Balmer shell around a z=7.64 quasar
Julien Wolf, Eduardo Bañados, Xiaohui Fan +25
Luminous quasars at the redshift frontier z>7 serve as stringent probes of super-massive black hole formation and they are thought to undergo much of their growth obscured by dense…
