GA-NIFS: sRMS, a new method for disentangling resolved and unresolved emission in integral field spectroscopy. Application to distant quasars
Michele Perna, Santiago Arribas, Carlota Prieto-Jiménez +28
The interpretation of AGN emission-line profiles in type1 AGN is often complicated by the dominance of bright, spatially unresolved nuclear continuum and broad-line region (BLR) em…
GA-NIFS view of LAP1: Assembly of Pop~III stellar clusters during EoR
J. Scholtz, R. Maiolino, S. Carniani +28
Lensed and Pristine 1 (LAP1) is one of the most promising candidates for the detection of so-called Pop~III stars at . In this work, we present new high-spectral-resoluti…
The search for Population III: Confirmation of a HeII emitter with no metal lines at z=10.6
Roberto Maiolino, Hannah Übler, Michele Perna +49
We report the confirmation of a HeII1640 emitter located at 3 pkpc from the galaxy GN-z11, at z=10.6. The detection, based on JWST NIRSpec-IFU high-resolution spectroscopy, conf…
GA-NIFS and JADES: Confirmation of pristine gas near GN-z11
Hannah Übler, Roberto Maiolino, Pablo G. Pérez-González +32
According to the leading cosmological model, a first generation of stars called Population III (PopIII), condensed almost entirely out of hydrogen and helium, must have initiated t…
GA-NIFS: Dissecting The Alchemised: JWST reveals turbulent metal-poor gas fuelling a co-spatial starburst in a complex system at
Robert G. Pascalau, Francesco D'Eugenio, Roberto Maiolino +25
Recent observations revealed that distant galaxies have bursty star formation histories, regulated by stellar or active galactic nuclei (AGN) feedback and gas inflows. According to…
The Little Blue and Red Dots Rosetta Stones: Non-Gaussian broad lines, hot dust, and X-ray weakness
M. Brazzini, F. D'Eugenio, R. Maiolino +31
The population of Active Galactic Nuclei (AGN) newly discovered by the James Webb Space Telescope (JWST) exhibits peculiar properties that distinguish it from both local type I AGN…
GA-NIFS: AGN activity in a Lyα emitter within a triple-AGN system anchored by a passive galaxy at z=3
Michele Perna, Santiago Arribas, Mahmoud Hamed +15
Massive quenched galaxies at z>3 challenge models of early galaxy evolution, as their rapid formation and abrupt quenching require efficient feedback, often linked to active galact…
GA-NIFS: high prevalence of dusty and metal-enriched outflows in massive and luminous star-forming galaxies at
B. Rodríguez Del Pino, S. Arribas, M. Perna +16
We present a search for and characterization of ionized outflows in 15 star-forming systems at with no evidence of Active Galactic Nuclei (AGN), observed with JWST/NIRSp…
The accretion of quasars at the epoch of reionisation: catches the primeval monsters slowly feasting
B. Trefoloni, E. Nardini, S. Carniani +8
Quasars (QSOs) emit an enormous amount of light as a result of the accretion of gas onto supermassive black holes (SMBHs). Thanks to their luminosity, the most distant known QSOs a…
GA-NIFS: Understanding the ionization nature of EGSY8p7/CEERS-1019. Evidence for a star formation-driven outflow at z = 8.6
Sandra Zamora, Stefano Carniani, Elena Bertola +16
Understanding the physical conditions and feedback mechanisms in early massive galaxies is essential to uncover how they formed and evolved during the first billion years of the Un…
GA-NIFS: A smouldering disk galaxy undergoing ordered rotation at z=4.26
Gareth C. Jones, Roberto Maiolino, Francesco D'Eugenio +13
Rotating galaxies with relaxed gaseous disks have been discovered across cosmic time, from the local Universe to high redshift (z>4). But few such sources have been confirmed at z>…
Doubling NIRSpec/IFS capability to calibrate the single-epoch black hole mass relation at high redshifts
Eleonora Parlanti, Bartolomeo Trefoloni, Stefano Carniani +6
The recent discovery of a large population of overmassive black holes (BHs) in the early Universe challenges the validity of the BH-host galaxy coevolution framework. However, the…
GA-NIFS: Powerful and frequent outflows in moderate-luminosity active galactic nuclei at
Giacomo Venturi, Stefano Carniani, Elena Bertola +18
The period between z ~ 3-6, a key transformational phase in galaxy evolution preceding 'cosmic noon' (z ~ 1-3), is very poorly explored in terms of feedback from AGN acting through…
GA-NIFS: an extended [OIII] halo around the sub-Eddington quasar J1342+0928 at z=7.54
Bartolomeo Trefoloni, Stefano Carniani, Elena Bertola +18
The James Webb Space Telescope (\textit{JWST}) opened a new observational window on the primordial Universe. Here we present new JWST NIRSpec integral field spectroscopy (IFS) obse…
High-Resolution Optical IFU Spectroscopy of the Complex Galaxy Merger II Zw 096
C. Riesco, E. Treister, G. Venturi +20
Luminous and Ultra-luminous IR galaxies ((U)LIRGs) are critical for investigating feedback mechanisms due to a combination of intense star formation (SF) episodes and active galact…
