Reionization driven by the few: the ionizing budget of galaxies at z=5-10 from JWST/NIRSpec

Emma Giovinazzo, Pascal A. Oesch, Anne Verhamme +5

The sources responsible for the Epoch of Reionization (EoR), the last major phase transition of the Universe, remain highly elusive. While JWST has begun to illuminate the properti…

Outflows in the Early Universe: Neutral gas Absorption in Galaxies at z > 3 from low-resolution JWST Spectroscopy

Matteo Sapori, Sirio Belli, Letizia Bugiani +14

Recent JWST/NIRSpec observations have shown that Na I D absorption tracing neutral gas outflows is widespread in massive galaxies at Cosmic Noon (-), but their prevalenc…

Spatial decomposition of Little Red Dots with JWST/NIRSpec IFU into broad-line red cores and narrow-line blue host galaxies

Yuzo Ishikawa, Anna-Christina Eilers, Rohan P. Naidu +11

Little Red Dots (LRDs) are a population of compact red sources discovered by the James Webb Space Telescope (JWST). Imaging and spectroscopy have shown that LRDs exhibit a complex…

JWST COSMOS-3D: Spectroscopic Census and Luminosity Function of [O III] Emitters at 6.75<z<9.05 in COSMOS

Romain A. Meyer, Feige Wang, Koki Kakiichi +38

We present a catalogue of spectroscopically selected [OIII]+Hb emitters at 6.75<z<9.05 and the resulting [OIII] 5008 Ã Luminosity Function (LF) in the COSMOS field. We leverage the…

A Census of the 200 Most Massive Galaxies Spectroscopically Observed with JWST at zspec 3-15

Mengyuan Xiao, Pascal A. Oesch, Longji Bing +26

Massive galaxies provide strong tests of galaxy formation models, yet a comprehensive spectroscopic view of their properties and demographics in the early Universe has remained elu…

Little Red Dots as Intermediate Mass, Super-Eddington Engines: Insights from Type IIn Supernovae and The 1837-1856 Great Eruption of Carinae

Rohan P. Naidu, Jorryt Matthee, Anna de Graaff +20

JWST's Little Red Dots (LRDs) display a unique constellation of features that do not occur simultaneously in any other class of galaxies or AGN. Here we observe that many of these…
