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…
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…
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…
