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…
LATED: Ly-anchored photometric selection of candidate metal-free and extremely metal-poor star formation from the end of reionisation to cosmic noon
Mingyu Li, Zheng Cai, Roberto Maiolino +24
Cosmological simulations allow a low-level tail of Population III (Pop III) star formation to persist to . Spectroscopic confirmation is expensive, so an efficient photometr…
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…
A Dusty Quenching-candidate AGN host at z=5.7: massive quiescent galaxies may quench already during the dust-obscured phase
Francesco D'Eugenio, Matilde Brazzini, Roberto Maiolino +12
We present a spectro-photometric analysis of RUBIES-EGS-9809, a broad-line AGN host at z=5.7 with a Balmer break and a dominant point source. The source is dust reddened (3 m…
Misaligned or chaotic? A strong break of axial symmetry in the local LRD J1025 revealed with VLT/FORS2 spectropolarimetry
Francesco D'Eugenio, Gabriele Pezzulli, Roberto Maiolino +18
Little Red Dots (LRDs) are compact active galactic nuclei (AGN) with unusual spectral energy distributions and broad Balmer emission, candidate signposts of rapid black-hole growth…
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…
JADES: the mass-metallicity relation at . New calibrations, extremely metal-poor galaxies, and chemical diversity
Yuki Isobe, Mirko Curti, Roberto Maiolino +28
We present gas-phase metallicities of star-forming galaxies at -10 with deep JWST/NIRSpec spectra from the JADES full data release, Dark Horse, and OASIS programmes. We stack…
JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: stellar population catalogue for galaxies in GOODS-N and GOODS-S
Qiao Duan, Sandro Tacchella, Benjamin D. Johnson +37
We present the galaxy stellar population catalogue from the JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5 (DR5), providing homogeneous Bayesian inference of physic…
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…
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>…
When relics were made: vigorous stellar rotation and low dark matter content in the massive ultra-compact galaxy GS-9209 at z=4.66
Robert G. Pascalau, Francesco D'Eugenio, Sandro Tacchella +24
JWST uncovered a large number of massive quiescent galaxies (MQGs) at , which theoretical models struggle to reproduce. Explaining the number density of such objects requires…
Galaxy Mergers in the Epoch of Reionization II: Major Merger-Triggered Star Formation and AGN Activities at 4.5-8.5
Qiao Duan, Qiong Li, Christopher J. Conselice +29
Galaxy mergers are a key driver of galaxy formation and evolution, including the triggering of AGN and star formation to a still unknown degree. We thus investigate the impact of g…
