(Abridged) We probe the merging channel of massive galaxies over the z=0.3-1.3 redshift window by studying close pairs in a sample of 238 galaxies with stellar mass >1E11Msun, from the deep (m<26.5AB, 3 sigma) SHARDS survey. SHARDS provides medium ba

Autor: Monelli, M., Milone, A. P., Stetson, P. B., Marino, A. F., Cassisi, S., Molina, A. Del Pino, Salaris, M., Aparicio, A., Asplund, M., Grundahl, F., Piotto, G., Weiss, A., Carrera, R., Cebrian, M., Murabito, S., Pietrinferni, A., Sbordone, L.

We present a general overview and the first results of the SUMO project (a SUrvey of Multiple pOpulations in Globular Clusters). The objective of this survey is the study of multiple stellar populations in the largest sample of globular clusters homo
