Galaxies caught in transition: the role of group environment in shaping the mass-size relation in the local Universe

Gissel P. Montaguth, Claudia Mendes de Oliveira, Ciria Lima-Dias +8

The stellar mass-size relation is a sensitive probe of how environment shapes galaxy structure. We analyse this relation in the local Universe for galaxies in compact groups (CGs),…

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…

Spatially Resolved Physical Properties of Young Star Clusters and Star-forming Clumps in the Brightest z>6 Galaxy, the Strongly Lensed Cosmic Spear at z=6.2

Abdurro'uf, Dan Coe, Tom Resseguier +49

We present spatially resolved analysis of stellar populations in the brightest galaxy known to date (AB mag 23), the strongly lensed MACS0308zD1 (dubbed the ``Cosmic Spear…

The intracluster light analysis of the most evolved systems of galaxies: fossil groups

Nícolas O. L. de Oliveira, Yolanda Jiménez-Teja, Renato A. Dupke +7

We present the analysis of the intracluster light (ICL) in three fossil groups (FG), RXJ085640.72+055347.36, RX J1136+0713, and RX J1410+4145, at z ~ 0.1. We used two optical broad…

Euclid preparation LXX. Forecasting detection limits for intracluster light in the Euclid Wide Survey

Euclid Collaboration, C. Bellhouse, J. B. Golden-Marx +292

The intracluster light (ICL) permeating galaxy clusters is a tracer of the cluster's assembly history, and potentially a tracer of their dark matter structure. In this work we expl…
