HELM's deep: Highly Extincted Low-Mass galaxies seen by JWST

L. Bisigello, G. Gandolfi, A. Grazian +25

The dust content of star-forming galaxies is generally positively correlated with their stellar mass. However, some recent JWST studies have shown the existence of a population of…

SHORES II: Multi-frequency Characterisation of the Sub-mJy Radio Population in FIR-selected Fields

Meriem Behiri, Marcella Massardi, Vincenzo Galluzzi +4

We present a new deep multi-frequency radio survey of two extragalactic fields observed with the Australia Telescope Compact Array (ATCA) as part of the SHORES project (Serendipito…

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…

Host galaxy identification of LOFAR sources in the Euclid Deep Field North

Bisigello L., Giulietti M., Prandoni I. +6

We present a catalogue of optical and near-infrared counterparts to radio sources detected in the Euclid Deep Field North (EDF-N) using observations from the LOw-Frequency ARray (L…

Sub-arcsecond-resolution LOFAR observations of bright sub-millimetre galaxies in the North Ecliptic Pole field

M. Bondi, I. Prandoni, M. Magliocchetti +6

Bright SMGs contribute significantly to the star formation rate (SFR) density (20-50\%) and stellar mass density ( 30-50\%) at 2-4 with SFRs M,yr$^{-1}…

An Updated Repository of Sub-mJy Extragalactic Source-Count Measurements in the Radio Domain

Vincenzo Galluzzi, Meriem Behiri, Marika Giulietti +1

We present an updated repository of sub-mJy extragalactic radio source counts between MHz and GHz, incorporating recent advances in radio surveys and observational techn…

StAGE: Stellar Archaeology-driven Galaxy Evolution

Michele Bosi, Andrea Lapi, Lumen Boco +10

We build a semi-empirical framework of galaxy evolution (dubbed StAGE) firmly grounded on stellar archaeology. The latter provides data-driven prescriptions that, on a population s…

SEMPER I. Radio Predictions for Star-Forming Galaxies at

M. Giulietti, I. Prandoni, M. Bonato +7

[Abridged] SFGs are the dominant population in the faint radio sky, corresponding to flux densities at 1.4 GHz mJy. A panchromatic approach is essential for selecting SFGs…

Euclid Quick Data Release (Q1). The active galaxies of Euclid

Euclid Collaboration, T. Matamoro Zatarain, S. Fotopoulou +355

We present a catalogue of candidate active galactic nuclei (AGN) in the Quick Release (Q1) fields. For each source we collect multi-wavelength photometry and spec…

Euclid Quick Data Release (Q1). Extending the quest for little red dots to z<4

Euclid Collaboration, L. Bisigello, G. Rodighiero +348

Recent James Webb Space Telescope (JWST) observations have revealed a population of sources with a compact morphology and a characteristic `v-shaped' continuum, namely blue at rest…

Going deeper into the dark with COSMOS-Web: JWST unveils the total contribution of Radio-Selected NIRfaint galaxies to the cosmic Star Formation Rate Density

Fabrizio Gentile, Margherita Talia, Andrea Enia +34

We present the first follow-up with JWST of radio-selected NIRfaint galaxies as part of the COSMOS-Web survey. By selecting galaxies detected at radio frequencies ($S_{\rm 3 GHz}>1…

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…
