MARTA: A "little" black hole hidden in a clumpy, metal-poor galaxy at z~3.8
Mirko Curti, Bianca Moreschini, Elisa Cataldi +20
JWST has extended the search for accreting black holes into the high-redshift, low-mass regime. We report a low-mass black hole candidate in MARTA 3887, a clumpy, metal-poor galaxy…
OASIS III: Bursty star formation drives observed galaxy sizes at

Tobias J. Looser, Francesco D'Eugenio, William M. Baker +19
Models of bursty star formation in low-mass (10^8-10^9.5 Msun) galaxies at z>4 differ most in the suppressed phases: what drives the decline, how fast star formation falls, and how…
OASIS I: Spectroscopy of Mini-Quenched and Lulling Galaxies Constrains the Quiet Side of Bursty Star Formation at z > 4
Tobias J. Looser, Francesco D'Eugenio, William M. Baker +19
JWST has revealed that star formation in early galaxies is bursty, including episodes of violent suppression, so-called mini-quenching. But these were largely serendipitous discove…
PRISMS GHZ8: Evidence for a Young Burst and Potential Merger Activity at z=10.23
Ruqiu Lin, Jorge Zavala, Javier Álvarez-Márquez +26
UV-bright galaxies in the early Universe provide important constraints on the rapid build-up of stellar mass and the sources responsible for cosmic reionization. However, the physi…

We present the first results of the ongoing INAF GTO program focused on the search of sub-arcsecond dual AGN, carried out with the near-infrared integral-field unit SPIFFIER of the…
ALMA2040: The High-Redshift Circumgalactic Medium. Imaging the fueling and feedback of galaxies in the early universe
Kirsty M. Butler, Justin Spilker, Seiji Fujimoto +23
Galaxies do not form in isolation, but rather as part of a wider interconnected web mediated at their interface by an extended gaseous atmosphere - the Circum-Galactic Medium (CGM)…
Probing cold gas and dust in quiescent galaxies across cosmic time
Anita Zanella, Sirio Belli, Belen Alcalde Pampliega +35
The discovery of massive quiescent galaxies at high redshift by JWST has revealed that star formation can cease rapidly in the early Universe, yet the physical mechanisms responsib…
Dust at cosmic dawn: unveiling the onset of dust and obscured star formation at
Hiddo Algera, Tom Bakx, Manuel Aravena +31
Although less than 1 percent of the baryonic mass budget of a galaxy, cosmic dust profoundly alters the multi-wavelength appearance of galaxies across cosmic time. The (sub)millime…
The dawn of the first galaxies
Livia Vallini, Tanio Diaz Santos, Belen Alcalde Pampliega +56
Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics. JWST has now revealed an unexpected population of ult…
Distilling Graph Geometry: Knowledge Gap from GNNs to MLPs
Zhewei Chen, Hao Zhu, Jiaojiao Jiang +1
GNN-to-MLP distillation aims to retain the predictive accuracy of a message-passing teacher while deploying a graph-free MLP at inference. Existing methods mainly transfer node-wis…
GA-NIFS view of LAP1: Assembly of Pop~III stellar clusters during EoR

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…
Exploring the observed properties of JWST Little Red Dots with cosmological simulations and dust radiative transfer
Saksham Chandna, Fabio Di Mascia, Simona Gallerani +6
JWST has uncovered compact high-redshift (z>=4) sources, dubbed Little Red Dots (LRDs), characterised by a distinct V-shaped continuum. Their nature remains debated since broad-lin…
Balmer Break Measurements Trace Departures from the Star-Forming Main Sequence at with JWST/NIRSpec

A. Deconto-Machado, G. Vietri, E. Piconcelli +22
Ultra-fast broad absorption line outflows (uBAL, ~0.1-0.2c) represent some of the most extreme manifestations of quasar-driven winds. We aim to investigate the variability of uBALs…
