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…
Witnessing the onset of reionisation via Lyman- emission at redshift 13
Joris Witstok, Peter Jakobsen, Roberto Maiolino +34
$\require{mediawiki-texvc}$Cosmic Reionisation commenced when ultraviolet (UV) radiation produced in the first galaxies began illuminating the cold, neutral gas that filled the pri…
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…
GA-NIFS: the interplay between merger, star formation and chemical enrichment in MACS1149-JD1 at z=9.11 with JWST/NIRSpec
Cosimo Marconcini, Francesco D'Eugenio, Roberto Maiolino +15
We present JWST/NIRSpec integral-field spectroscopy observations of the z ~ 9.11 lensed galaxy MACS1149-JD1, as part of the GA-NIFS programme. The data was obtained with both the G…
GA-NIFS: Multi-phase analysis of a star-forming galaxy at
Eleonora Parlanti, Stefano Carniani, Giacomo Venturi +16
In this study, we present a detailed multiphase analysis of HZ4, a main-sequence star-forming galaxy at z ~ 5.5, known for being a turbulent rotating disk and having a detection of…
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…
GA-NIFS: JWST/NIRSpec IFS view of the z~3.5 galaxy GS5001 and its close environment at the core of a large-scale overdensity
Isabella Lamperti, Santiago Arribas, Michele Perna +19
We present JWST NIRSpec observations in IFS mode of the galaxy GS5001 at redshift z=3.47, the central member of a candidate protocluster in the GOODS-S field. The data cover a fiel…
Net-zero gas inflow: Measurement of the gas consumption history of a massive quiescent galaxy
Jan Scholtz, Francesco D'Eugenio, Roberto Maiolino +23
JWST is discovering increasing numbers of quiescent galaxies 1--2 billion years after the Big Bang, whose redshift, high mass, and old stellar ages indicate that their formation an…
Spectroscopic confirmation of two luminous galaxies at
Stefano Carniani, Kevin Hainline, Francesco D'Eugenio +42
The first observations of JWST have revolutionized our understanding of the Universe by identifying for the first time galaxies at . In addition, the discovery of many lum…
GA-NIFS: Witnessing the complex assembly of a star-forming system at
Gareth C. Jones, Andrew J. Bunker, Kseniia Telikova +19
We present observations of the Lyman-break galaxy HZ10 with the JWST/NIRSpec IFU in high and low spectral resolution (G395H, spectral resolving power and PRI…
Accelerated quenching and chemical enhancement of massive galaxies in a gas-rich halo
Pablo G. Pérez-González, Francesco D`Eugenio, Bruno Rodríguez del Pino +18
Stars in galaxies form when baryons radiatively cool down and fall into gravitational wells whose mass is dominated by dark matter. Eventually, star formation quenches as gas is de…
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…
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…
A dormant, overmassive black hole in the early Universe
Ignas Juodžbalis, Roberto Maiolino, William M. Baker +25
Recent observations have found a large number of supermassive black holes already in place in the first few hundred million years after Big Bang. The channels of formation and grow…
