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,…
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…
AGN STORM 2: IX. Studying the Dynamics of the Ionized Obscurer in Mrk 817 with High-resolution X-ray Spectroscopy
Fatima Zaidouni, Erin Kara, Peter Kosec +45
We present the results of the XMM-Newton and NuSTAR observations taken as part of the ongoing, intensive multi-wavelength monitoring program of the Seyfert 1 galaxy Mrk 817 by the…
JWST meets Chandra: a large population of Compton thick, feedback-free, and intrinsically X-ray weak AGN, with a sprinkle of SNe
Roberto Maiolino, Guido Risaliti, Matilde Signorini +22
We investigate the X-ray properties of a sample of 71 broad line and narrow line AGN at 2z11 discovered by JWST in the GOODS fields, which have the deepest Chandra observatio…
Quasars as standard candles VI: spectroscopic validation of the cosmological sample
Bartolomeo Trefoloni, Elisabeta Lusso, Emanuele Nardini +5
A sample of quasars has been recently assembled to investigate the non-linear relation between their monochromatic luminosities at 2500Å, and 2 keV and to exploit quasars as a new…
Building the high-redshift Hubble Diagram with quasars
Matilde Signorini, Guido Risaliti, Andrea Sacchi +2
Proceeding of the "HACK100" Conference, 6-10 June 2022, Trieste, Italy - In recent years, quasars have been shown to be reliable standardizable candles, thanks to the non-linear re…
