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…

Nearly pristine gas in a galaxy 1 billion years after the Big Bang

Sarah E. I. Bosman, Frederick B. Davies, Louise Welsh +22

Excitation of carbon and oxygen ions is the primary mechanism by which collapsing gas clouds dissipate heat to form new stars. At early cosmic times, in galaxies with chemically pr…

: 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.…

Rapid radio variability in the blazar VLASS J04100139: Indication of a hidden population of weak radio jets at Cosmic Dawn

Silvia Belladitta, Eduardo Bañados, Anniek J. Gloudemans +7

Doppler boosting allows blazars to be detected out to high-, making them promising probes of the intergalactic medium through the 21 cm forest. We report 0.14411 GHz observat…

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…
