Environmental dependence in the halo model informed by the FLAMINGO simulations

G. Martín Girardi, D. Rana, H. Hoekstra +2

Galaxy-galaxy lensing (GGL) measurements around galaxy samples in different environments provide valuable information about the galaxy-halo connection. In such studies the halo mod…

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…

Euclid Quick Data Release (Q1). Searching for radio-selected \Euclid-dark galaxies in the EDF-N

Euclid Collaboration, M. Giulietti, I. Prandoni +308

We present and investigate the properties of a sample of radio-selected, Euclid-dark galaxies, identified from LOFAR HBA observations at 144 MHz within the Euclid Deep Field-North…

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…

Euclid Quick Data Release (Q1): Identification of massive galaxy candidates at the end of the Epoch of Reionisation

Euclid Collaboration, R. Navarro-Carrera, K. I. Caputi +295

Probing the presence and properties of massive galaxies at high redshift is one of the most critical tests for galaxy formation models. In this work, we search for galaxies with st…

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…

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…

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…

Spectroscopic confirmation of a dust-obscured, metal-rich dwarf galaxy at z~5

L. Bisigello, G. Gandolfi, A. Feltre +24

We present the first spectroscopic confirmation of a dust-obscured dwarf galaxy, CEERS-14821. The analysis is performed combining JWST NIRCam broad-band photometry and NIRSpec/PRIS…

What are the Pillars of Reionization? Revising the AGN Luminosity Function at z~5

Andrea Grazian, Emanuele Giallongo, Konstantina Boutsia +22

In the past, high-z AGNs were given a minor role as possible drivers of reionization, despite initial evidences in favor of their large space densities at low luminosities by Chand…

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…
