Deep X-ray View of a Distant Protocluster Anchored by a Quasar at : No Evidence for Enhanced X-ray AGN Activity

Shouyi Wang, Feige Wang, Jinyi Yang +22

Whether dense environments accelerate SMBH growth during cosmic reionization remains uncertain because X-ray constraints on protoclusters are rare. We analyze ks of…

: 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…

Extreme Enrichment at Cosmic Dawn: Three FeII-Strong Quasars at z > 6 from the JWST Aether survey

Anniek J. Gloudemans, Emanuele Paolo Farina, Roberto Decarli +22

We present three outliers on the quasar main sequence at z>6, as revealed by JWST/NIRSpec IFU observations from the Aether survey, a program targeting ~200 quasars at cosmic dawn.…

Overmassive No More: The Case for Little Red Dots Hosting Black Hole Seeds as Massive as Single Supermassive Stars

Wendy Q. Sun, Rohan P. Naidu, Hanpu Liu +17

Little Red Dots (LRDs) display singular properties unlike any known class of AGN or galaxies, motivating novel mass estimators for their central engines. Inspired by their similari…

SHELLQs. Black Hole Mass and Eddington Ratio Distributions of Intermediate-Luminosity Quasars at 6<z<7

Masafusa Onoue, John D. Silverman, Yoshiki Matsuoka +31

We present near-infrared spectroscopy of 21 quasars at 6.07 < z < 6.90 obtained with JWST/NIRSpec and Subaru/MOIRCS. These targets have absolute ultraviolet magnitudes of -25 < M_1…

The ionizing properties of JWST's compact broad-line emitters

Sara Mascia, Jorryt Matthee, Alberto Torralba +4

The recent JWST discovery of a numerous population of broad-line emitters (BLEs) at has reopened the question of whether sources other than faint galaxies contributed signifi…
