The deepest X-ray view of a kiloparsec scale jet at z=6.1

Fabio A. Meanti, Luca Ighina, Alberto Moretti +7

The mechanism responsible for the high-energy emission observed in kiloparsec-scale jets across cosmic time remains poorly understood. The relativistic jet associated with the z=6.…

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…

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…

The most extreme high-z radio quasars in the eRASS:1 X-ray survey

L. Ighina, L. Palmieri, L. N. Martínez-Ramírez +7

We present the selection and identification of high-z radio quasars from a combination of X-ray (eROSITA All-Sky Survey), optical/NIR (DECam Local Volume Exploration), and radio (R…

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…
