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…
Quantifying Spectroscopic Flux Variations Between JWST NIRISS and NIRSpec: Slit Losses in Emission Line Measurements of z1-3 Galaxies
Nicolò Dalmasso, Peter J. Watson, Tommaso Treu +9
We analyze JWST NIRISS and NIRSpec spectroscopic observations in the Abell 2744 galaxy cluster field. From approximately 120 candidates, we identify 12 objects with at least a prom…
Extreme equivalent width-selected low-mass starbursts at : insights into their role in cosmic reionization
M. Llerena, L. Pentericci, R. Amorín +22
We investigate the properties of extreme emission line galaxies (EELGs) at and their role in reionization. Compact, low-mass galaxies with intense optical emission lines ar…
Ly visibility from z = 4.5 to 11 in the UDS field: Evidence for a high neutral hydrogen fraction and small ionized bubbles at z 7
L. Napolitano, L. Pentericci, M. Dickinson +28
The resonant scattering nature of Ly photons interacting with neutral hydrogen makes Ly emitters (LAEs) robust tracers of the intergalactic neutral hydrogen fraction, and thu…
A Lyman continuum analysis for galaxies at in the Abell 2744 Cluster Field
Y. Liu, S. Mascia, L. Pentericci +17
Identifying Lyman continuum (LyC) leakers at intermediate redshifts is crucial for understanding the properties of cosmic reionizers, as the opacity of the intergalactic medium (IG…
Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions
Casey Papovich, Justin W. Cole, Weida Hu +27
Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…
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…
Little impact of mergers and galaxy morphology on the production and escape of ionizing photons in the early Universe
S. Mascia, L. Pentericci, M. Llerena +28
Compact, star-forming galaxies with high star formation rate surface densities () are often efficient Lyman continuum (LyC) emitters at , likely as inten…
