Simulations of collision and sloshing in the galaxy group NGC 5098/5096

Richards P. Albuquerque, Gastão B. Lima Neto, Rubens E. G. Machado +2

The study of galaxy groups is essential to understanding the evolutionary history of large-scale structures in the Universe. These dense environments have a significant impact on g…

Galaxy groups in various evolutionary stages

Kethelin Parra Ramos, C. Adami, N. Clerc +10

The formation process of galaxy groups is not yet fully understood. In particular, that of fossil groups (FGs) is still under debate. Due to the relative rarity of FGs, large sampl…

Low Surface Brightness structures from annotated deep CFHT images: effects of the host galaxy's properties and environment

Elisabeth Sola, Pierre-Alain Duc, Mathias Urbano +20

Hierarchical galactic evolution models predict that mergers drive galaxy growth, producing low surface brightness (LSB) tidal features that trace galaxies' late assembly. These fai…

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…

Structure and kinematics of the interacting group NGC 5098/5096

G. B. Lima Neto, H. V. Capelato, F. Durret +1

Most galaxies in the Universe are found in groups, which have various morphologies and dynamical states. Studying how groups evolve is an important step for our understanding in bo…

UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey

Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86

The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
