Resumen:
We have performed a statistical analysis of minor and major mergers selected from SDSS-DR7. We build a galaxy pair catalog requiring rp < 25 kpc/h and DeltaV < 350 km/s within redshift z<0.1. We have carried out an eye-ball classification of images according to the evidence of interaction through distorted morphologies and tidal features. We find that the characteristics of the interactions (disturbed/non-disturbed pairs) and the ratio of luminosity galaxy pair members involved in a merger are important parameters in setting galaxy properties.
