Unveil the nature of JWST-AGN and Little Red Dots with SKAO continuum surveys
Giovanni Mazzolari, Dharam V. Lal, Isabella Prandoni +6
The advent of JWST has revealed a large population of AGN at , which are dex more abundant than previously expected, including also the enigmatic population of Little…
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…
Radio selection of heavily obscured AGN in the J1030 field: unraveling a missing Compton-thick population
Giovanni Mazzolari, Roberto Gilli, Marco Mignoli +21
We tested the effectiveness of radio selection to discover heavily obscured AGNs, particularly at high-z, and we measured their abundance for the first time from a radio perspectiv…
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…
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,…
Narrow line AGN selection in CEERS: spectroscopic selection, physical properties, X-ray and radio analysis
Giovanni Mazzolari, Jan Scholtz, Roberto Maiolino +11
In this work, we spectroscopically select narrow-line AGNs (NLAGNs) among the ~300 publicly available medium-resolution spectra of the Cosmic Evolution Early Release Science Survey…
