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…
Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr
E. Vanzella, F. Loiacono, M. Messa +38
We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…
A quasar-galaxy merger at : rapid host growth via accretion of two massive satellite galaxies
Roberto Decarli, Federica Loiacono, Emanuele Paolo Farina +38
We present JWST/NIRSpec Integral Field Spectroscopy in the rest-frame optical bands of the system PJ308-21, a quasar at caught as its host galaxy interacts with companio…
Euclid preparation. Observational expectations for redshift z<7 active galactic nuclei in the Euclid Wide and Deep surveys
Euclid Collaboration, M. Selwood, S. Fotopoulou +260
We forecast the expected population of active galactic nuclei (AGN) observable in the Euclid Wide Survey (EWS) and Euclid Deep Survey (EDS). Starting from an X-ray luminosity funct…
New AGN diagnostic diagrams based on the [OIII] auroral line
G. Mazzolari, H. Übler, R. Maiolino +8
The James Webb Space Telescope (JWST) is revolutionizing our understanding of black holes formation and growth in the early Universe. However, JWST has also revealed that some of t…
COSMOS2020: Investigating the AGN-obscured accretion phase at via [NeV] selection
L. Barchiesi, C. Vignali, F. Pozzi +7
We investigated the properties of 94 [NeV]3426AA-selected type 2 AGN in COSMOS at z=0.6-1.2, performing optical-to-far-infrared spectral energy distribution fitting. In addition, w…
A quasar-galaxy merger at : black hole mass and quasar properties from the NIRSpec spectrum
Federica Loiacono, Roberto Decarli, Marco Mignoli +31
We present JWST/NIRSpec integral field data of the quasar PJ308-21 at . As shown by previous ALMA and HST imaging, the quasar has two companion sources, interacting with…
Heavily Obscured AGN detection: a Radio vs X-ray challenge
Giovanni Mazzolari, Roberto Gilli, Marcella Brusa +11
In this work, we study the AGN radio detection effectiveness in the major deep extragalactic surveys, considering different AGN obscuration levels, redshift, and AGN bolometric lum…
