GA-NIFS: The highly overdense system BR1202-0725 at z 4.7. A double AGN with fast outflows plus eight companion galaxies
S. Zamora, Giacomo Venturi, Stefano Carniani +14
Distant quasars (QSOs) in galaxy overdensities are considered key actors in the evolution of the early Universe. In this work, we studied the kinematic and physical properties of t…
GA-NIFS: interstellar medium properties and tidal interactions in the evolved massive merging system B14-65666 at z=7.152
Gareth C. Jones, Rebecca A. A. Bowler, Andrew J. Bunker +13
We present JWST/NIRSpec IFU observations of the z=7.152 galaxy system B14-65666, as part of the GA-NIFS survey. Line and continuum emission in this massive system (log10(M*/Msol)=9…
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…
GA-NIFS: ISM properties and metal enrichment in a merger-driven starburst during the Epoch of Reionisation probed with JWST and ALMA
J. Scholtz, M. Curti, F. D'Eugenio +17
We present deep JWST/NIRSpec integral-field spectroscopy (IFS) and ALMA [CII]158m observations of COS-3018, a star-forming galaxy at z6.85, as part of the GA-NIFS progr…
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…
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…

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…
