A Cosmic Archipelago of lensed metal-poor galaxies at

A. Bolamperti, M. Messa, A. Zanella +21

The Cosmic Archipelago is an ensemble of galaxies, strongly lensed by the cluster MACSJ0416, showing extreme physical properties at . We combine JWST/NIRCam with deep VL…

Strong Lensing Model and Dust Extinction Maps of the Host Galaxy of Type Ia Supernova H0pe

A. Galan, S. Schuldt, G. B. Caminha +11

Strong gravitational lensing by massive galaxy clusters offers rare opportunities to observe multiple images of distant () Type Ia supernovae (SNe) and to resolve the…

JWST spectroscopic confirmation of the Cosmic Gems arc at z=9.625 -- Insights into the small scale structure of a post-burst system

M. Messa, E. Vanzella, F. Loiacono +30

We present JWST/NIRSpec integral field spectroscopy of the Cosmic Gems arc, strongly magnified by the galaxy cluster SPT-CL J06155746. Six-hour integration using NIRSpec prism s…

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…
