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,…
HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
HYPERION. Shedding light on the first luminous quasars: A correlation between UV disc winds and X-ray continuum
A. Tortosa, L. Zappacosta, E. Piconcelli +41
One of the main open questions in the field of luminous () quasars (QSOs) at is the rapid formation (Gyr) of their superm…
The near-infrared SED of blue quasars: what drives the evolution of the dusty torus?
Bartolomeo Trefoloni, Roberto Gilli, Elisabeta Lusso +5
A fundamental ingredient in the unified model of active galactic nuclei (AGN) is the obscuring torus, whose innermost, hottest region dominates the near infrared (NIR) emission. Ch…
The Dual Nature of GHZ9: Coexisting Active Galactic Nuclei and Star Formation Activity in a Remote X-ray Source at z = 10.145
Lorenzo Napolitano, Marco Castellano, Laura Pentericci +33
We present James Webb Space Telescope (JWST)/NIRSpec PRISM spectroscopic characterization of GHZ9 at z= 10.145 0.010, currently the most distant source detected by the Chandr…
An X-ray Significantly Variable, Luminous, Type 2 Quasar at z = 2.99 with a Massive Host Galaxy
Xiurui Zhao, Stefano Marchesi, Marco Ajello +8
We present a comprehensive X-ray analysis and spectral energy distribution (SED) fitting of WISEA J171419.96+602724.6, an extremely luminous type 2 quasar at = 2.99. The source…
