Holes in the BH? AGN signatures in the FUV spectrum of a black-hole dominated Little Red Dot at
Xihan Ji, Gabriele Pezzulli, Francesco D'Eugenio +15
It has been suggested that "Little Red Dots" (LRDs) might be accreting black holes enshrouded by dense gas in a nearly closed geometry, which completely covers the central black ho…
The possible accretion discs of GN-z11 at redshift z = 10.6, MoM-z14 at z = 14.44 and other high redshift objects
A. C. Fabian, J. Jiang, W. M. Baker +4
The JWST has enabled the discovery of Active Galactic Nuclei at high redshifts. The intrinsic UV spectrum of GN-z11 at redshift z=10.6 has a spectral slope compatible with a standa…
Lord of LRDs: Insights into a "Little Red Dot" with a low-ionization spectrum at z = 0.1
Xihan Ji, Francesco D'Eugenio, Ignas Juodžbalis +14
Recent observations by the James Webb Space Telescope (JWST) have revealed a puzzling population of optically red and compact galaxies with peculiar "V"-shaped spectra at high reds…
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,…
BlackTHUNDER -- A non-stellar Balmer break in a black hole-dominated little red dot at
Xihan Ji, Roberto Maiolino, Hannah Ãbler +34
Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called ``Little Red Dots'' (LRDs) at , many of wh…
Another view into JWST-discovered X-ray weak AGNs via radiative dusty feedback
W. Ishibashi, A. C. Fabian, R. Maiolino +2
JWST has revealed a previously unknown population of low-luminosity active galactic nuclei (AGN) in the early Universe. These JWST-AGN at high redshifts are characterised by a set…
