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…

Charting the expansion of the Universe from z0 to z14 with HII galaxies

R. Chávez, R. Terlevich, A. L. González-Morán +14

We present an updated Hubble diagram of giant extragalactic H II regions and H II galaxies spanning the redshift interval to , extending the use of the $L(\math…

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…
