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…

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.…

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…

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…
