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…

A Selection Aware View of Black Hole-Galaxy Coevolution at High Redshift

Francesco Ziparo, Stefano Carniani, Simona Gallerani +1

The large population of broad-line Active Galactic Nuclei (AGN) observed with the James Webb Space Telescope (JWST) at opens a new window onto the black hole-galaxy c…

E-XQR-30: Evidence for an Increase in the Ionization State of Metal Absorbers from z~6 to z~2

Stephanie Rowlands, R. L. Davies, E. Ryan-Weber +15

We investigate the evolution of the ionization state of metal-enriched gas in and around galaxies near the epoch of reionization using a sample of 488 metal absorption systems at 4…

Updated dark pixel fraction constraints on reionization's end from the Lyman-series forests of XQR-30

Frederick B. Davies, Sarah E. I. Bosman, Valentina D'Odorico +16

The fraction of "dark pixels" in the Ly and other Lyman-series forests at provides a powerful constraint on the end of the reionization process. Any spectral region…

Multi-wavelength properties of LISA detectable events

Srija Chakraborty, Simona Gallerani, Fabio Di Mascia +5

We investigate the intrinsic and observational properties of galaxies hosting coalescing massive black holes (MBHs) that gives rise to gravitational waves (GWs) detect…

Red, hot, and very metal poor: extreme properties of a massive accreting black hole in the first 500 Myr

Roberta Tripodi, Nicholas Martis, Vladan Markov +29

The James Webb Space Telescope (JWST) has recently discovered a new population of objects at high redshift referred to as `Little Red Dots' (LRDs). Their nature currently remains e…
