GA-NIFS: A galaxy-wide outflow in a Compton-thick mini-BAL quasar at z = 3.5 probed in emission and absorption
Michele Perna, Santiago Arribas, Xihan Ji +17
Studying the distribution and properties of ionised gas in outflows driven by AGN is crucial for understanding the feedback mechanisms at play in extragalactic environments. In thi…
The missing FeII bump in faint JWST AGN: possible evidence for metal-poor broad-line regions at early cosmic times
Bartolomeo Trefoloni, Xihan Ji, Roberto Maiolino +6
Recent JWST observations have revealed a large population of intermediate/low-luminosity AGN at early times with peculiar properties, different from local AGN or luminous quasars.…
The eventful life of a luminous galaxy at z = 14: metal enrichment, feedback, and low gas fraction?
Stefano Carniani, Francesco D'Eugenio, Xihan Ji +25
JADES-GS-z14-0 is the most distant spectroscopically confirmed galaxy yet, at . With a UV magnitude of -20.81, it is one of the most luminous galaxies at cosmic dawn and its…
JWST/NIRSpec WIDE survey: a z=4.6 low-mass star-forming galaxy hosting a jet-driven shock with low ionisation and solar metallicity
Francesco D'Eugenio, Roberto Maiolino, Vijay H. Mahatma +14
We present NIRSpec/MSA observations from the JWST large-area survey WIDE, targeting the rest-frame UV-optical spectrum of Ulema, a radio-AGN host at redshift z=4.6348. The low-reso…
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…
Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe
Callum Witten, William McClymont, Nicolas Laporte +12
While JWST has observed galaxies assembling as early as , evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) -- the descendan…
JADES -- The Rosetta Stone of JWST-discovered AGN: deciphering the intriguing nature of early AGN
Ignas Juodžbalis, Xihan Ji, Roberto Maiolino +23
JWST has discovered a large population of Active Galactic Nuclei (AGN) at high redshift. Many of these newly discovered AGN have broad permitted lines (typically H), but are ext…
JADES: The star-formation and chemical enrichment history of a luminous galaxy at z~9.43 probed by ultra-deep JWST/NIRSpec spectroscopy
Mirko Curti, Joris Witstok, Peter Jakobsen +30
We analyse ultra-deep JWST observations of the galaxy JADES-GS-z9-0 at z = 9.4327, and derive detailed stellar and interstellar medium (ISM) properties of this luminous (MUV=-20.43…
The density-bounded twilight of starbursts in the early Universe
William McClymont, Sandro Tacchella, Francesco D'Eugenio +8
The peculiar nebular emission displayed by galaxies in the early Universe presents a unique opportunity to gain insight into the regulation of star formation in extreme environment…
JADES -- The small blue bump in GN-z11: insights into the nuclear region of a galaxy at z=10.6
Xihan Ji, Roberto Maiolino, Gary Ferland +14
We report the detection of continuum excess in the rest-frame UV between 3000 Å and 3550 Å in the JWST/NIRSpec spectrum of GN-z11, a luminous galaxy . The shape of the co…
JWST meets Chandra: a large population of Compton thick, feedback-free, and intrinsically X-ray weak AGN, with a sprinkle of SNe
Roberto Maiolino, Guido Risaliti, Matilde Signorini +22
We investigate the X-ray properties of a sample of 71 broad line and narrow line AGN at 2z11 discovered by JWST in the GOODS fields, which have the deepest Chandra observatio…
JADES Data Release 3 -- NIRSpec/MSA spectroscopy for 4,000 galaxies in the GOODS fields
Francesco D'Eugenio, Alex J. Cameron, Jan Scholtz +51
We present the third data release of JADES, the JWST Advanced Deep Extragalactic Survey, providing both imaging and spectroscopy in the two GOODS fields. Spectroscopy consists of m…
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…
GA-NIFS: An extremely nitrogen-loud and chemically stratified galaxy at
Xihan Ji, Hannah Übler, Roberto Maiolino +11
We report the chemical abundance pattern of GS\_3073, a galaxy at which was previously confirmed to host an overmassive active black hole, by leveraging the detection of a…
Resolving the nature and putative nebular emission of GS9422: an obscured AGN without exotic stars
Sandro Tacchella, William McClymont, Jan Scholtz +27
Understanding the sources that power nebular emission in high-redshift galaxies is fundamentally important not only for shedding light onto the drivers of reionisation, but to cons…
