Accretion of minor satellites has been postulated as the most likely mechanism to explain the significant size evolution of the massive galaxies over cosmic time. A direct way of probing this scenario is to measure the frequency of satellites around massive galaxies at different redshifts. In this contribution, I present the study that we have performed to search for satellites around 629 massive ({M}_* ˜ 10^{11} {M}_{&sun;}) galaxies up to z˜2 from the near-infrared Palomar/DEEP-2 survey. We find that the fraction of massive galaxies with satellites remains basically constant and close to 30% for satellites with a mass ratio down to 1:100 up to z=1, and ˜15% for satellites with a 1:10 mass ratio up to z=2. In addition, at low redshift the satellites are, in average, 1.5 Gyr younger than the massive galaxies that host them. In the minor merging model, this rejuvenated material is likely to be placed in the outskirts of the massive objects, and negative age gradients should be observed in local massive galaxies. Hence, this work gives new clues to explore the minor merging scenario from the study of nearby galaxies.
