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…

JWST Reveals Compact Nuclear Starbursts Masquerading as AGNs in Metal-Poor Dwarfs: Where Are the Accreting Intermediate-Mass Black Holes?

William Matzko, Shobita Satyapal, Jeffrey D. Mckaig +19

We present JWST/NIRSpec spectroscopy of the low-mass, metal-poor galaxy SDSS~J160135.95+311353.7 (J1601), selected for its extreme mid-infrared colors and compact nuclear emission,…

MICONIC: The multiphase circumnuclear region of Centaurus A as seen with JWST/MIRI MRS observations. I. Spectral inventory and properties of the warm molecular disk

L. Evangelista, P. Guillard, J. Martin +21

Supermassive black holes power Active Galactic Nuclei (AGN), injecting energy that regulates accretion and shapes host galaxies. We investigate the morphology, excitation, and kine…

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: 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…

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…
