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…
JADES: Dynamical Measurements of Dark Matter Halo Masses at Using Galaxy Pairs
Zihao Wu, Daniel J. Eisenstein, Benjamin D. Johnson +13
We present dynamical measurements of dark matter halo masses at using galaxy pairs. Galaxy pairs in the early Universe are usually in their first infall, before substan…
GA-NIFS: The interplay between feedback and star formation at 3 < z < 9 probed by JWST/NIRSpec IFU
L. Ulivi, M. Perna, S. Arribas +24
The study of starburst- and AGN-driven feedback is fundamental for understanding the processes that shape galaxy growth, quench star formation, and drive the co-evolution of galaxi…
Intense and extended CIII] emission suggests a strong outflow in JADES-GS-z14-0
Stefano Carniani, Peter Jakobsen, Giacomo Venturi +31
JWST has revealed an overabundance of very bright, blue galaxies at z>10, raising fundamental questions about how star formation and feedback operate at Cosmic Dawn. We present new…
Metal Mayhem at z~7-10: Diversity and Evolution of Gas-Phase Metallicity Gradients
Maria Koller, Roberto Maiolino, Hannah Übler +16
We present a JWST/NIRSpec Integral Field Unit (IFU) study of metallicity gradients in seven low-metallicity systems at . The main sample spans stellar masses of $\rm \lo…
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…
Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity
Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +61
We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…
JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: Photometric Catalog
Brant E. Robertson, Benjamin D. Johnson, Sandro Tacchella +34
JADES Data Release 5 (DR5) photometric catalogs and describes the methodologies used for source detection, deblending, photometry, uncertainty estimation, and catalog curation. The…
JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: NIRCam Imaging in GOODS-S and GOODS-N
Benjamin D. Johnson, Brant E. Robertson, Daniel J. Eisenstein +30
We present the Near Infrared Camera (NIRCam) imaging products of the fifth data release (DR5) of the James Webb Space Telescope (JWST) Advanced Deep Extragalactic Survey (JADES). T…
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…
JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: Photometrically Selected Galaxy Candidates at z > 8

We present a sample of 2081 sources selected at photometric redshift across the JADES DR5 data release in GOODS-S and GOODS-N over a total area of 469 squar…
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…
