Galaxy evolution in compact groups II. Witnessing the influence of major structures in their evolution

Gissel P. Montaguth, Antonela Monachesi, Sergio Torres-Flores +15

Compact groups (CGs) of galaxies are extreme environments for morphological transformations and the cessation of star formation. Though initially considered isolated, it is now rec…

The role of supercluster filaments in shaping galaxy clusters

Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44

In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We i…

Galaxy evolution in compact groups - III. Structural analysis of galaxies and dynamical state of non-isolated compact groups

Gissel P. Montaguth, Ana Laura O'Mill, Claudia Mendes de Oliveira +17

Compact Groups (CGs) of galaxies are dense systems where projected separations are comparable to their optical diameters. A subset - non-isolated CGs - are embedded within major st…

The S-PLUS Fornax Project (S+FP): A first 12-band glimpse of the Fornax galaxy cluster

A. V. Smith Castelli, A. Cortesi, R. F. Haack +40

The Fornax galaxy cluster is the richest nearby (D ~ 20 Mpc) galaxy association in the southern sky. As such, it provides a wealth of oportunities to elucidate on the processes whe…
