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…
Image simulations of highly magnified clumpy galaxies
Irene Mini, Massimo Meneghetti, Matteo Messa +5
We present ClumPyLen, a Python-based simulator designed to produce realistic mock observations of strongly lensed, high-redshift, clumpy star-forming galaxies. The tool models gala…
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…
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…
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…
GAMA 526784: the progenitor of a globular cluster-rich ultra-diffuse galaxy? II. Molecular gas, neutral gas and environment
Maria Luisa Buzzo, Anita Zanella, Michael Hilker +3
Aims. We investigate the gas reservoirs, star formation (SF) properties, and environment of the ultra-diffuse galaxy GAMA526784 to understand its formation history, the efficiency…
GAMA 526784: the progenitor of a globular cluster-rich ultra-diffuse galaxy? I. Star clusters, stellar body and ionised gas properties
Maria Luisa Buzzo, Michael Hilker, Anita Zanella +4
Context. Ultra-diffuse galaxies (UDGs) are an intriguing population of galaxies. Despite their dwarf-like stellar masses and low surface brightness, they have large half-light radi…
SIEGE IV: compact star clusters in cosmological simulations with high star formation efficiency and sub-parsec resolution
R. Pascale, F. Calura, E. Vesperini +10
The formation of compact high-redshift star-forming clumps, the physical processes driving their evolution and their potential connection to present-day Globular Clusters are key o…
Unraveling the Lyman Continuum Emission of Ion3: Insights from HST multi-band imaging and X-Shooter spectroscopy
U. Meštrić, E. Vanzella, A. Beckett +15
We provide a comprehensive analysis of Ion3, the most distant LyC leaker at , using multi-band HST photometry and X-Shooter spectroscopy. Deep HST F390W imaging probe unco…
Spatially resolved [CII]-gas conversion factor in early galaxies
L. Vallini, A. Pallottini, M. Kohandel +12
Determining how efficiently gas collapses into stars at high-redshift is key to understanding galaxy evolution in the Epoch of Reionization (EoR). Globally, this process is quantif…
Constraining the geometry of the gas surrounding a typical galaxy at with Ly polarization
A. Bolamperti, S. -J. Chang, J. Vernet +6
Ly emission is the strongest tracer of recombining ionized hydrogen in young, star-forming galaxies, but its origin is still debated. Ly arises when emitted photons scatter i…
