Tracing AGN-Galaxy Co-Evolution with UV Line-Selected Obscured AGN

Luigi Barchiesi, Lucia Marchetti, Mattia Vaccari +11

Understanding black hole-galaxy co-evolution and the role of AGN feedback requires complete AGN samples, including heavily obscured systems. In this work, we present the first UV l…

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 Pristine Star-Forming Complex at z=4.19

E. Vanzella, M. Messa, A. Zanella +14

We report the discovery of a faint (M_1700 ~ -12.2), oxygen-deficient strongly-lensed ionizing source -- dubbed LAP2 (Lensed And Pristine 2) -- at a spectroscopic redshift of z=4.1…

The properties of X-ray selected AGN in protoclusters pinpointed by Enormous Lya Nebulae

A. Traina, F. Vito, F. Arrigoni-Battaia +11

Protoclusters of galaxies are overdense regions of the Universe characterized by large gas reservoirs. Such environments make them perfect laboratories to investigate galaxy-AGN co…

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…
