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…

JWST's PEARLS: resolved study of the stellar and dust components in starburst galaxies at cosmic noon
M. Polletta, B. L. Frye, N. Garuda +35
Dusty star-forming galaxies (DSFGs) contribute significantly to the stellar buildup at cosmic noon. Major mergers and gas accretion are often invoked to explain DSFGs' prodigious s…
