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 (effe…
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…
Parametric strong lensing model of the galaxy cluster Abell 2390 from Euclid and MUSE observations
D. Abriola, M. Lombardi, C. Grillo +14
We present a new high precision parametric strong lensing total mass reconstruction of the Euclid Early Release Observations (ERO) galaxy cluster Abell 2390, at redshift z = 0.231.…
