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…

Aether-SHELLQs: JWST integral-field spectroscopy of candidate obscured quasars at z ~ 6

Yoshiki Matsuoka, Roberto Decarli, Emanuele Paolo Farina +12

We present James Webb Space Telescope (JWST) NIRSpec integral field unit (IFU) observations of six galaxies at , obtained as part of the Aether project (General Observers…

A 6.2 Quasar on the Local M- Relation Quenching Its Host Galaxy from the Aether Survey

Weizhe Liu, Emanuele Paolo Farina, Xiaohui Fan +19

We report JWST/NIRSpec integral field unit (IFU) observations of the quasar J15124422 at from the Aether survey. At 900 Myr after the Big Bang, this object al…

Extreme Galaxy-scale Outflows Are Frequent among Luminous Early Quasars

Weizhe Liu, Xiaohui Fan, Huan Li +23

The existence of abundant post-starburst/quiescent galaxies just 1-2 Gyrs after the Big Bang challenges our current paradigm of galaxy evolution. Cosmological simulations sug…

4MOST ChANGES: Catalog of high-redshift quasar candidates (4.5 < < 7) selected with SED fitting

T. Mkrtchyan, C. Mazzucchelli, R. J. Assef +12

The identification of high-redshift quasars () is critical for studying the early Universe, supermassive black hole growth, and cosmic reionization. Most known high-redshi…

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--[…
