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 t…

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…

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…

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…

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…

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…
