The eventful life of a luminous galaxy at z = 14: metal enrichment, feedback, and low gas fraction?
Stefano Carniani, Francesco D'Eugenio, Xihan Ji +25
JADES-GS-z14-0 is the most distant spectroscopically confirmed galaxy yet, at . With a UV magnitude of -20.81, it is one of the most luminous galaxies at cosmic dawn and its…
JADES: Measuring reionization properties using Lyman-alpha emission
Gareth C. Jones, Andrew J. Bunker, Aayush Saxena +19
Ly is the transition to the ground state from the first excited state of hydrogen (the most common element). Resonant scattering of this line by neutral hydrogen greatly impedes…
Witnessing the onset of reionisation via Lyman- emission at redshift 13
Joris Witstok, Peter Jakobsen, Roberto Maiolino +34
$\require{mediawiki-texvc}$Cosmic Reionisation commenced when ultraviolet (UV) radiation produced in the first galaxies began illuminating the cold, neutral gas that filled the pri…
21 Balmer Jump Street: The Nebular Continuum at High Redshift and Implications for the Bright Galaxy Problem, UV Continuum Slopes, and Early Stellar Populations
Harley Katz, Alex J. Cameron, Aayush Saxena +11
We study the physical origin and spectroscopic impact of extreme nebular emission in high-redshift galaxies. The nebular continuum, which can appear during an extreme starburst, is…
JADES: Physical properties of Ly and non-Ly emitters at z ~ 4.8-9.6
Nimisha Kumari, Renske Smit, Joris Witstok +21
We investigate the physical properties of Lyman-alpha emitters (LAEs) and non-Lyman-alpha emitters (non-LAEs) at z4.8--9.6 via a stacking analysis of 253 JWST/NIRSpec spectra…
Spectroscopic confirmation of two luminous galaxies at
