The accretion of quasars at the epoch of reionisation: catches the primeval monsters slowly feasting
B. Trefoloni, E. Nardini, S. Carniani +8
Quasars (QSOs) emit an enormous amount of light as a result of the accretion of gas onto supermassive black holes (SMBHs). Thanks to their luminosity, the most distant known QSOs a…
Doubling NIRSpec/IFS capability to calibrate the single-epoch black hole mass relation at high redshifts
Eleonora Parlanti, Bartolomeo Trefoloni, Stefano Carniani +6
The recent discovery of a large population of overmassive black holes (BHs) in the early Universe challenges the validity of the BH-host galaxy coevolution framework. However, the…
GA-NIFS: Understanding the ionization nature of EGSY8p7/CEERS-1019. Evidence for a star formation-driven outflow at z = 8.6
Sandra Zamora, Stefano Carniani, Elena Bertola +16
Understanding the physical conditions and feedback mechanisms in early massive galaxies is essential to uncover how they formed and evolved during the first billion years of the Un…
The radio properties of the JWST-discovered AGN
G. Mazzolari, R. Gilli, R. Maiolino +23
We explore the radio emission of JWST-selected Broad Line AGN (BLAGN, or type 1) in the GOODS-N field. We use deep radio data at different frequencies (144\,MHz, 1.5\,GHz, 3\,GHz,…
Narrow line AGN selection in CEERS: spectroscopic selection, physical properties, X-ray and radio analysis
Giovanni Mazzolari, Jan Scholtz, Roberto Maiolino +11
In this work, we spectroscopically select narrow-line AGNs (NLAGNs) among the ~300 publicly available medium-resolution spectra of the Cosmic Evolution Early Release Science Survey…
The X-rayUV Luminosity Relation of eROSITA Quasars
Andrea Sacchi, Guido Risaliti, Matilde Signorini +3
The non-linear relation between the UV and X-ray luminosity in quasars has been studied for decades. However, as we lack a comprehensive model able to explain it, its investigation…
