: 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…
BAQARO: Tracing Stochastic Black Hole Growth Histories and Quasar Lightcurves in a Cosmological Context
Elia Pizzati, Joseph F. Hennawi, Joop Schaye
How supermassive black holes (BHs) assemble their mass and power the luminous quasars we observe across cosmic time remain central open questions in galaxy evolution. We present BA…
Quasar Impostors: Two Extremely UV-Bright () Reionisation-Epoch Galaxies Powered by Very Massive Stars
Daming Yang, Joseph F. Hennawi, Sarah E. I. Bosman +20
The extreme bright end of the galaxy UV luminosity function during reionisation remains poorly constrained, particularly where the galaxy and quasar luminosity functions overlap an…
The Lumina Project: The Demographics of Active Galactic Nuclei from Quasars to Little Red Dots at
Xuejian Shen, Oliver Zier, Aaron Smith +16
High-redshift active galactic nuclei (AGN) serve as powerful probes of early black-hole growth, galaxy formation, and the evolving intergalactic medium (IGM). In this work, we use…
The Impact of Cosmic Variance and Satellites on JWST Clustering Measurements at Redshift around 6
Jiamu Huang, Elia Pizzati, Joseph F. Hennawi +4
We present a framework for inferring the dark matter halo masses of quasars and [O III]-emitting galaxies from JWST/NIRCam Wide Field Slitless Spectroscopy (WFSS) clustering measur…
MEOW: The increase in the obscured AGN fraction in mid-infrared from 0 < z < 6 with JWST MIRI
Teodora-Elena Bulichi, Gene C. K. Leung, Anna-Christina Eilers +16
Obscured active galactic nuclei (AGN) are often invoked to explain the rapid emergence of young quasars at high redshift and are crucial for building a complete census of AGN activ…
Clustering of z~6.6 Quasars and [O III] Emitters Constrains Host Halo Masses and Duty Cycles in 25 ASPIRE Fields
Jiamu Huang, Joseph Hennawi, Elia Pizzati +21
We use data from the JWST ASPIRE Wide Field Slitless Spectroscopy (WFSS) program to measure the auto-correlation function of [O,{\sc iii}] emitters at 5.37.0 and the quasar--[…
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…
