In order to understand and distinguish the diverse environmental processes transforming galaxies, it is fundamental to resolve its impact on the galaxy, either in terms of its dynamical state, stellar population, or chemical abundance. Using data from the S-PLUS survey, we selected two samples of interacting galaxies. The first group is composed of galaxies that are probably interacting but with no confirmation as cluster members. For this group, we propose to use GMOS spectroscopy to observe 19 of these to (1) confirm that candidates are actually physical systems by measuring the redshift, (2) identify the nature of the nuclear activity of the galaxy using emission line ratios, (3) study the underlying stellar population using the continuum shape and main absorption lines. The second group is composed of 24 interacting galaxies with confirmation as physical systems. For this sample, we propose to use GMOS imaging to understand the extension of the gas component and the nature of the interaction. All galaxies observed arein the outskirts of the Fornax and Hydra clusters and the fact that we have already detected Halpha in the S-PLUS images for the proposed galaxies makes them very probable members of the clusters.
