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 Quasar Feedback Survey: Ionised Outflows in type 2 QSOs with MUSE data

M. Bianchin, C. M. Harrison, T. Costa +13

We study ionised gas properties in a sample of 18 luminous (log L erg/s) obscured QSOs at 0.085<z<0.2 observed with VLT/MUSE as part of the multi-wavelength Quasa…

Rapid growth in a dual AGN during a gas-rich merger at z~4.5

Hyewon Suh, Roberto Decarli, Emanuele Paolo Farina +15

The late stages of galaxy mergers - when two supermassive black holes (SMBHs) reach kiloparsec-scale separations - represent a critical phase for understanding SMBH growth, galaxy…

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…

The imprint of AGN-driven outflows on the CGM: the case of Lyα nebulae around high-z quasars

Silvia C. Rueda-Vargas, Vincenzo Mainieri, Giulia Tozzi +5

Some cosmological hydrodynamical simulations predict that outflows driven by active galactic nuclei (AGN) play a key role in powering the Ly nebulae observed around high-redshif…

Beneath the Surface: >85% of z>5.9 QSOs in Massive Host Galaxies are UV-Faint

R. J. Bouwens, E. Banados, R. Decarli +20

We use [CII] observations of a large quasi-stellar object (QSO) sample to segregate sources by host galaxy mass, aiming to identify those in the most massive hosts. [CII] luminosit…
