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: Dissecting the multiple sub-structures and probing their complex interactions in the \Lyalpha emitter galaxy CR7 at z = 6.6 with JWST/NIRSpec
C. Marconcini, F. D'Eugenio, R. Maiolino +16
We present JWST/NIRSpec integral field spectroscopic (IFS) observations of the \Lyalpha emitter CR7 at z ~ 6.6, observed as part of the GA-NIFS program. Using low-resolution PRISM…
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 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.…
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…
JWST/NIRSpec insights into the circumnuclear region of Arp 220: A detailed kinematic study
L. Ulivi, M. Perna, I. Lamperti +13
The study of starburst and active galactic nuclei (AGN) feedback is crucial for understanding the regulation of star formation and the evolution of galaxies across cosmic time. Arp…
Feedback and ionized gas outflows in four low-radio power AGN at z 0.15
L. Ulivi, G. Venturi, G. Cresci +19
An increasing number of observations and simulations suggests that low-power (<10 erg s) jets may be a significant channel of feedback produced by active galactic nuc…
HOMERUN a new approach to photoionization modelling. I -- reproducing observed emission lines with percent accuracy and obtaining accurate physical properties of the ionized gas
A. Marconi, A. Amiri, A. Feltre +26
We present HOMERUN (Highly Optimized Multi-cloud Emission-line Ratios Using photo-ionizatioN), a new approach to modelling emission lines from photoionized gas that can simultaneou…
