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…
The Dual Nature of GHZ9: Coexisting Active Galactic Nuclei and Star Formation Activity in a Remote X-ray Source at z = 10.145
Lorenzo Napolitano, Marco Castellano, Laura Pentericci +33
We present James Webb Space Telescope (JWST)/NIRSpec PRISM spectroscopic characterization of GHZ9 at z= 10.145 0.010, currently the most distant source detected by the Chandr…
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…
Mapping the Hubble Flow from z0 to z7.5 with HII Galaxies
Ricardo Chávez, Roberto Terlevich, Elena Terlevich +7
Over twenty years ago, Type Ia Supernovae (SNIa) observations revealed an accelerating Universe expansion, suggesting a significant dark energy presence, often modelled as a cosmol…
Evidence of extreme ionization conditions and low metallicity in GHZ2/GLASS-z12 from a combined analysis of NIRSpec and MIRI observations
Antonello Calabro, Marco Castellano, Jorge A. Zavala +19
GHZ2/GLASS-z12 has been recently observed by JWST with both NIRSpec and MIRI spectrographs, making it the most distant galaxy () with complete spectroscopic coverag…
JWST NIRSpec Spectroscopy of the Remarkable Bright Galaxy GHZ2/GLASS-z12 at Redshift 12.34
Marco Castellano, Lorenzo Napolitano, Adriano Fontana +28
We spectroscopically confirm the mag galaxy GHZ2/GLASS-z12 to be at redshift . The source was selected via NIRCam photometry in GLASS-JWST ERS data, p…
