Investigating ionising sources and the complex interstellar medium of GHZ2 at
M. Castellano, L. Napolitano, B. Moreschini +27
An accurate characterisation of the physical properties of galaxies at cosmic dawn is key to understanding the origin of the high abundance of UV-bright galaxies at z10. W…
The Collective Voice of Ly Emitters: Insights from JWST Stacked Spectroscopy
R. Tripodi, L. Napolitano, L. Pentericci +22
We present a spatially resolved stacked analysis of 287 LAEs at observed with JWST/NIRSpec prism spectroscopy. By constructing a two-dimensional stack from public surveys (CA…
The AGN nature of strong CIII emitters in the Early Universe with JWST
F. Arevalo-Gonzalez, R. Tripodi, M. Llerena +21
The semi-forbidden CIII] 1907,1909 doublet is a key tracer of high-ionization emission in the early universe. We present a study of CIII] emission in galaxies at z=5-7, using…
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…
The ionizing photon production efficiency of star-forming galaxies at
M. Llerena, L. Pentericci, L. Napolitano +27
Investigating the ionizing emission of star-forming galaxies is critical to understanding their contribution to reionization and their impact on the surrounding environment. The nu…
Seven wonders of Cosmic Dawn: JWST confirms a high abundance of galaxies and AGNs at z 9-11 in the GLASS field
L. Napolitano, M. Castellano, L. Pentericci +24
We present JWST/NIRSpec PRISM follow-up of candidate galaxies at z=9-11 selected from deep JWST/NIRCam photometry in GLASS-JWST Early Release Science data. We spectroscopically con…
