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…

CHAMPS: The COSMOS High-Redshift ALMA-MIRI Population Survey - A New Census of the Dusty Early Universe

Andreas L. Faisst, Felix Martinez, Jeyhan S. Kartaltepe +86

Understanding how dust forms and evolves over cosmic time is a key open problem in extragalactic astrophysics. Galaxies in the early Universe were once thought to be mostly dust-po…

An empirical derivation of the average dust attenuation law at 2<z<7

Giulia Rodighiero, Gaia Edes Esposito, Daniela Calzetti +12

Dust attenuation affects galaxy SEDs and introduces uncertainties in star formation rates, stellar masses, and metallicities. Direct spectroscopic constraints at early cosmic epoch…

JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime

E. Iani, P. Rinaldi, A. Torralba +35

We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…

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…

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…

Pushing JWST to the extremes: search and scrutiny of bright galaxy candidates at z15-30

M. Castellano, A. Fontana, E. Merlin +50

We designed customized Lyman-break color selection techniques to identify galaxy candidates in the redshift ranges and . The selection was pe…

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…
