GA-NIFS: The interplay between feedback and star formation at 3 < z < 9 probed by JWST/NIRSpec IFU
L. Ulivi, M. Perna, S. Arribas +24
The study of starburst- and AGN-driven feedback is fundamental for understanding the processes that shape galaxy growth, quench star formation, and drive the co-evolution of galaxi…
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 Little Blue and Red Dots Rosetta Stones: Non-Gaussian broad lines, hot dust, and X-ray weakness
M. Brazzini, F. D'Eugenio, R. Maiolino +31
The population of Active Galactic Nuclei (AGN) newly discovered by the James Webb Space Telescope (JWST) exhibits peculiar properties that distinguish it from both local type I AGN…
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…
A thin disk and a nearly universal accretion rate in luminous quasars
G. Risaliti, B. Trefoloni, M. Salvati
Quasars accretion models predict a broad range of optical and ultraviolet properties that depend primarily on black hole mass and accretion rate. Yet, most optically selected lumin…
Little Red and Blue Dots: simply stratified Broad Line Regions
J. Scholtz, F. D'Eugenio, R. Maiolino +14
It has been claimed that a fraction of the so-called Little Red Dots (LRDs) are characterised by exponential broad line profiles, which have been ascribed to broadening from electr…
Quasars as high-redshift standard candles
A. Sacchi, G. Risaliti, M. Signorini +10
The non-linear relation between the X-ray and ultraviolet (UV) luminosity in quasars has been used to derive quasar distances and to build a Hubble diagram at redshifts up to $z\si…
The X-ray-to-UV relation does not evolve in homogeneous quasar samples
G. Risaliti, E. Lusso, E. Nardini +6
We present a new, highly homogeneous quasar sample with X-ray and UV observations optimized to reliably estimate distances via the non-linear X-ray-to-UV relation. Cross-matching t…
