What can we learn from the Nitrogen abundance of High-z galaxies?
Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge +9
We present measurements of the gas-phase Oxygen and Nitrogen abundances obtained by applying the direct method to JWST NIRspec spectroscopy for 6 galaxies at redshift g…

Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr
E. Vanzella, F. Loiacono, M. Messa +38
We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…

Anatomy of a z=6 Lyman-α emitter down to parsec scales: extreme UV slopes, metal-poor regions and possibly leaking star clusters
Matteo Messa, E. Vanzella, F. Loiacono +31
We present a detailed JWST/NIRSpec and NIRCam analysis of a gravitationally-lensed galaxy () at redshift 6.14 magnified by the Hubble Frontier Field galaxy cluster MAC…
