We present results on the study of the stellar population in early-type galaxies (ETGs) belonging to 151 compact groups (CGs). We also selected a field sample composed of 846 ETGs to investigate environmental effects on galaxy evolution. We find that

We used optical imaging and spectroscopic data to derive substructure estimates for local Universe (z < 0.11) galaxy clusters from two different samples. The first was selected through the Sunyaev–Zel’dovich (SZ) effect by the Planck satellite, a

Conselho Nacional de Desenvolvimento Científico e Tecnológico In this work, we investigated differences between stellar populations of galaxies that are part of a cluster with and without substructures. We used optical spectra obtained from Sloan D
