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…

Resolved Maps of Gas and Dust in a Massive Quiescent Galaxy at z=2 from INQUEST-JWST: Evidence of Accretion and Rejuvenation

Sai Gangula, Andrew B. Newman, Meng Gu +10

Quiescent galaxies in the distant universe exhibit a range of gas content that may indicate a variety of quenching processes are at play. Mapping the distribution and kinematics of…

A faint M Lyman-continuum leaker candidate in the epoch of reionization: Unprecedented Ly properties at z=5.725

M. Messa, E. Vanzella, T. Morishita +10

We report the unprecedented Ly properties of AMORE6, an extremely metal-poor (), low-mass (), and ultracompact (effec…

Gas excitation of post-starburst galaxies at 0.6 < z < 1.3

A. Zanella, S. Belli, F. M. Valentino +1

Molecular gas traces the fuel for star formation and the processes that regulate it. Observing its physical state (e.g. excitation) reveals when and why galaxies quench. We observe…

A Pristine Star-Forming Complex at z=4.19

E. Vanzella, M. Messa, A. Zanella +14

We report the discovery of a faint (M_1700 ~ -12.2), oxygen-deficient strongly-lensed ionizing source -- dubbed LAP2 (Lensed And Pristine 2) -- at a spectroscopic redshift of z=4.1…

The z = 9.625 Cosmic Gems Galaxy was a "Compact Blue Monster" Propelled by Massive Star Clusters

E. Vanzella, M. Messa, A. Adamo +36

The recent discovery of five massive stellar clusters at z=9.625 in the Cosmic Gems has raised the question about the formation mechanism of star clusters in the first half Gyr aft…
