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…

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…

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…

Insights into jet-NLR energetics in PMN J0948+0022

B. Dalla Barba, L. Foschini, M. Berton +8

The analysis of the optical spectra of PMN J0948+0022 showed significant variations in the spectral lines that, when combined with the Fermi -ray light curve and radio observat…

Revised optical classification of a sample of gamma-ray emitting AGN with GTC and VLT

B. Dalla Barba, L. Foschini, M. Berton +10

We report the results of the optical follow-up of a sample of -ray-emitting active galactic nuclei (AGN). New high-quality optical spectra were obtained using Gran Telescopio C…

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…
