Resumen:
Recently, several observational works have provided evidence in favor of
a pre-processing of galaxies at moderate environments. These evidences
show that the transition of galaxies onto the red-sequence could take
place in galaxy groups in the outskirt of clusters or in the infalling
populations. Based on the evidence that interacting and merging systems
are priviledged found at intermediate densities, we use the SDSS-DR4
data to analyse the role of mergers and close galaxy interactions as
environmental processes to lead to evolutionary transformations. We
explore the properties of galaxy pairs and merging systems at different
local and global density environ- ments, comparing them with those of
isolated galaxies in an unbiased con- trol sample.
