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…
LATED: JWST integral field spectroscopy of a galaxy caught in chemical infancy at behind Abell 2744
Mingyu Li, Roberto Maiolino, Zheng Cai +26
When Population III (Pop III) star formation ended remains an open question. LATED-1 is an intrinsically faint () Ly emitter at revealed by VLT/MU…
The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
How to raise a supermassive black hole: interpreting early JWST AGN with the AESOPICA simulations
Sophie Koudmani, Jan Scholtz, Anthony J. Taylor +11
The active black holes uncovered by JWST in the early Universe are highly abundant and seemingly overmassive with respect to local scaling relations, challenging standard models of…
BlackTHUNDER Reveals a Massive Filament around a Compact AGN at
Giulia Tozzi, Hannah Übler, Eleonora Parlanti +27
Despite the growing number of compact active galactic nuclei (AGN) at discovered by JWST, their formation and evolution remain poorly understood. This paper investigates the…
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…
The Cliff: A Metal-Poor Little Red Dot Hosting an Overmassive Black Hole at
Lucy R. Ivey, Francesco D'Eugenio, Roberto Maiolino +18
JWST has revealed a large population of massive black holes (BHs) in the early Universe with unusual properties which mark them as distinct from low-redshift active galactic nuclei…
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…
Holes in the BH? AGN signatures in the FUV spectrum of a black-hole dominated Little Red Dot at
Xihan Ji, Gabriele Pezzulli, Francesco D'Eugenio +15
It has been suggested that "Little Red Dots" (LRDs) might be accreting black holes enshrouded by dense gas in a nearly closed geometry, which completely covers the central black ho…
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…
Not all protoclusters host evolved galaxies: Evidence for reduced environmental effects in a lower halo mass protocluster at
Callum Witten, Pascal A. Oesch, Jake S. Bennett +5
The progenitors of present-day galaxy clusters offer crucial insight into how galaxies and large-scale structure co-evolve in the early Universe. We present JWST/NIRCam grism spect…
BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy
Hannah Übler, Giovanni Mazzolari, Roberto Maiolino +41
We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…
A direct black hole mass measurement in a Little Red Dot at the Epoch of Reionization
Ignas Juodžbalis, Cosimo Marconcini, Francesco D'Eugenio +37
Recent discoveries of faint active galactic nuclei (AGN) at the redshift frontier have revealed a plethora of broad \Halpha emitters with optically red continua, named Little Red D…
Exploring Spatially-Resolved Metallicities, Dynamics and Outflows in Low-Mass Galaxies at
L. R. Ivey, J. Scholtz, A. L. Danhaive +18
A majority of JWST/NIRSpec/IFU studies at high redshifts to date have focused on UV-bright or massive objects, while our understanding of low-mass galaxies at early cosmic times re…
