No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
JWST-discovered AGN: evidence for heavy obscuration in the type-2 sample from the first stacked X-ray detection
Andrea Comastri, Giorgio Lanzuisi, Fabio Vito +9
One of the most puzzling properties of the high-redshift AGN population recently discovered by JWST, including both broad-line and narrow-line sources, is their X-ray weakness. Wit…
A big red dot at cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +22
We report the discovery of a little red dot (LRD), dubbed BiRD ('big red dot'), at in the field around the quasar SDSSJ1030+0524. Using NIRCam images, we identifie…
Unveiling faint X-ray AGN populations in the NewAthena era: Insights from cosmological simulations
Nuno Covas, Israel Matute, Stergios Amarantidis +7
Recent observations expanded our understanding of galaxy formation and evolution, yet key challenges persist in the X-ray regime, crucial for studying Active Galactic Nuclei (AGN).…
Intervening nuclear obscuration changing the X-ray look of the QSO CFHQS J164121+375520
Fabio Vito, William Nielsen Brandt, Andrea Comastri +16
X-ray observations of the optically selected QSO CFHQS J164121+375520 (hereafter J1641) revealed that its flux dropped by a factor from 2018, when it was a bri…
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…
