Title: Triplets of Quasars as lighthouses of galaxy and structure formation

Abstract: Triplets of quasars can be used as ``lighthouses'' to find forming structures. We propose a photometric study of the environments of two quasar triplets at z=1.3 and 1.5 with the Blanco 4m telescope. We plan to observe these triplets in the R and z' bands with the CCD Mosaic Imager and in the J and Ks bands with ISPI. With this multicolor photometry we will be able to detect associated galaxy groups and clusters, describe their morphology, and study the photometric properties of individual galaxies in their neighborhoods.
