Dynamical models of cluster members to probe the total mass properties of cluster subhalos. I. A comparison with parametric strong lensing models
Nicola Bianchetti, Claudio Grillo, Giovanni Granata +6
In this series of papers, we present dynamical models of cluster members in strong lensing (SL) galaxy clusters to independently probe the persistent discrepancy reported between S…
Euclid preparation. Probing galaxy evolution within cosmic voids in Euclid-like simulations
Euclid Collaboration, G. Papini, O. Cucciati +294
The evolution of galaxies is profoundly influenced by the environment in which they reside. Cosmic voids serve as pristine laboratories for studying galaxy evolution in the relativ…
A Consistent Implementation of Cluster Strong Lensing in Cosmological Simulation Light Cones
Cian Roche, Mark Vogelsberger, Michael McDonald +9
Galaxy cluster strong gravitational lensing plays a central role in precision cosmology, yet robust theoretical predictions have lagged behind an abundance of high-quality strong l…
A New Perspective on Galactic Evolution: Studying the Outskirts of the Abell S1063 Galaxy Cluster
L. Pecoraro, A. Mercurio, M. Annunziatella +14
Galaxy physical properties are influenced by their environments, but the processes responsible for mass and environmental quenching and structural transformations remain debated. G…
Euclid: Early Release Observations -- The extended stellar component of the IC10 dwarf galaxy
F. Annibali, A. M. N. Ferguson, P. M. Sanchez-Alarcon +175
We present a detailed analysis of the old, extended stellar component of the Local Group dwarf galaxy IC 10 using deep resolved-star photometry in the VIS and NISP bands of the Euc…
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…
