Resumen:
In this work we present preliminary results of our analysis of Optical (COSMOS) and IR (ISPI) data on the galaxy environment of 3 triplets of quasars at z ~ 1.5. The results are consistent with those found at low redshift. The quasars at z > 1 are not in the center of galaxy overdensities and they appear to follow the largescale structure. Moreover, the neighbourhoods of the triplets on smaller scales seem to have bluer galaxies.
