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…
CHAMPS: Data Reduction and Detection of ~3300 Dusty Galaxies at 1.2 mm
Felix Martinez, Jeyhan S. Karaltepe, Andreas L. Faisst +52
We present the reduction and source catalogs for the \textit{COSMOS High- ALMA-MIRI Population Survey} (CHAMPS), the largest Atacama Large (Sub)Millimeter Array (ALMA) blank fie…
: 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.…
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 Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
