An Attenuation Bump at z=9.3: Probing Dust Diversity at Cosmic Dawn
Giulia Rodighiero, Santiago Álvarez-Córdoba, Michele Catone +46
We report the identification of a UV attenuation bump in the Black Pearl, a galaxy at a spectroscopic redshift of 9.3335 observed with JWST/NIRSpec as part of the ZENITH and EMBER…
An HI+radio continuum study of local cluster galaxies: Intercepting the early stages of environmental processing with MeerKAT
Alessandro Ignesti, Paolo Serra, Alessandro Bianchetti +14
The evolution of galaxies in clusters is driven by their interaction with the environment, which deeply affects and alters the properties of the multi-phase interstellar medium. He…
EGS-z11-R0: a red, dust-rich galaxy at Cosmic Dawn
Giulia Rodighiero, Andrea Ferrara, Michele Catone +16
Context. Galaxies discovered by JWST at z > 10 are predominantly characterized by extremely blue rest-frame UV slopes. Conversely, the existence of dust-reddened systems at such ea…
Euclid: The first statistical census of dusty and massive objects in the ERO/Perseus field
G. Girardi, A. Grazian, G. Rodighiero +175
Our comprehension of the history of star formation at relies on rest-frame UV observations, yet this selection misses the most dusty and massive sources, yielding an incomple…
Mysteries of Capotauro: investigating the puzzling nature of an extreme F356W-dropout
Giovanni Gandolfi, Giulia Rodighiero, Marco Castellano +38
JWST has uncovered a diverse population of extreme near-infrared dropouts, including ultra high-redshift () galaxy candidates, dust-obscured galaxies challenging dust product…
Atomic hydrogen reservoirs in quiescent galaxies at z = 0.4
A. Bianchetti, G. Rodighiero, D. Donevski +11
Context. Based on Local Universe observations, quiescent galaxies (QGs) host lower to no HI compared to star-forming galaxies (SFGs), but no constraints have been derived so far at…
MIGHTEE-HI: The direct detection of neutral hydrogen in galaxies at
Matt J. Jarvis, Madalina N. Tudorache, I. Heywood +18
Atomic hydrogen constitutes the gas reservoir from which molecular gas and star formation in galaxies emerges. However, the weakness of the line means it has been difficult to dire…
Semi-empirical constraints on the HI mass function of star-forming galaxies and at from interferometric surveys
Francesco Sinigaglia, Alessandro Bianchetti, Giulia Rodighiero +5
The HI mass function is a crucial tool to understand the evolution of the HI content in galaxies over cosmic times. We aim to derive semi-empirical constraints at by c…
New constraints on the evolution of the MHI-M* scaling relation combining CHILES and MIGHTEE-HI data
Alessandro Bianchetti, Francesco Sinigaglia, Giulia Rodighiero +23
The improved sensitivity of interferometric facilities to the 21-cm line of atomic hydrogen (HI) enables studies of its properties in galaxies beyond the local Universe. In this wo…
Euclid Quick Data Release (Q1). An investigation of optically faint, red objects in the Euclid Deep Fields
Euclid Collaboration, G. Girardi, G. Rodighiero +326
Our understanding of cosmic star-formation at used to largely rely on rest-frame UV observations. However, these observations overlook dusty and massive sources, resulting in…
The multi-wavelength Tully-Fisher relation in the TNG50 cosmological simulation
Maarten Baes, Andrea Gebek, Sabelo Kunene +8
The Tully-Fisher relation (TFR) is one of the most important and widely used empirical correlations in extragalactic astronomy. Apart from its importance as a secondary distance in…
Ultra High-Redshift or Closer-by, Dust-Obscured Galaxies? Deciphering the Nature of Faint, Previously Missed F200W-Dropouts in CEERS
G. Gandolfi, G. Rodighiero, L. Bisigello +42
The James Webb Space Telescope (JWST) is revolutionizing our understanding of the Universe by unveiling faint, near-infrared dropouts previously beyond our reach, ranging from exce…
MIGHTEE-HI: deep spectral line observations of the COSMOS field
I. Heywood, A. A. Ponomareva, N. Maddox +16
The MIGHTEE survey utilises the South African MeerKAT radio telescope to observe four extragalactic deep fields, with the aim of advancing our understanding of the formation and ev…
An optically-dark merging system at z~6 detected by JWST
Giulia Rodighiero, Andrea Enia, Laura Bisigello +16
Near- to mid-Infrared observations (from Spitzer and JWST) have revealed a hidden population of galaxies at redshift z=3-6, called optically-dark objects, which are believed to be…
The impact of stellar bars on star-formation quenching: Insights from a spatially resolved analysis in the local Universe
Letizia Scaloni, Giulia Rodighiero, Andrea Enia +8
Stellar bars are common morphological structures in the local Universe; according to optical and NIR surveys, they are present in about two-thirds of disc galaxies. These elongated…
Ancient stellar populations in the outskirts of nearby grand-design spirals: Investigation of their star formation histories
Cristina Maria Lofaro, Giulia Rodighiero, Andrea Enia +7
The main sequence (MS) of star-forming galaxies (SFGs) is the tight relation between the galaxy stellar mass and its star formation rate (SFR) and was observed up to z ~ 6. The MS…
