Hedorah, the first yellow supergiant Kaiju star candidate at revealed by JWST behind AS1063

J. M. Diego, J. M. Palencia, C. Goolsby +8

We present a new free-form lens model for the galaxy cluster AS1063, based on previously spectroscopically confirmed lensed galaxies and new JWST images from the GLIMPSE…

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…

Euclid Quick Data Release (Q1). The first catalogue of strong-lensing galaxy clusters

Euclid Collaboration, P. Bergamini, M. Meneghetti +375

We present the first catalogue of strong lensing galaxy clusters identified in the Euclid Quick Release 1 observations (covering ). This catalogue is the resu…

Compact Size, High SFR: Defining Morphological Features of Ly-Emitters

Keunho Kim, Anahita Alavi, Christopher Snapp-Kolas +7

The mechanisms of Ly photon escape are key to understanding galaxy evolution and cosmic reionization, yet remain poorly understood. We investigate the UV-continuum sizes of 23 L…

Euclid: Early Release Observations -- A preview of the Euclid era through a galaxy cluster magnifying lens

H. Atek, R. Gavazzi, J. R. Weaver +200

We present the first analysis of the Euclid Early Release Observations (ERO) program that targets fields around two lensing clusters, Abell 2390 and Abell 2764. We use VIS and NISP…
