tokens: The authors wish to thank the referee, Dan Taranu, for his thorough revision of the manuscript and insightful comments and suggestions, which have helped to improve both the justification of the initial conditions of our simulations and the presentation of the results. This work was supported by the Programme for Promotion of High-Level Scientific and Technical Research of Spain under contracts AYA2010-15169 and AYA2013-40609-P. The simulations of the present work have been performed with the Computer Service Infrastructure of the Spanish Instituto de Astrofísica de Andalucía (IAA). This research is part of the IDILICO (Investigation of the DIffuse LIght COmponent in CGs of galaxies) project, an international collaboration that runs simulations of the formation of groups of galaxies using high-performance computing resources (see our website at http://www.am.ub.edu/extragalactic/idilico/ ). Initially born to shed light on the origin of the unusually large fractions of diffuse IGL found in some CGs of galaxies, IDILICO has now among its goals the creation of a comprehensive and unbiased sample of forming galaxy associations suited for investigating the aspects of galaxy evolution governed by gravitational dynamics, especially those driven by the multiple interactions and mergers that galaxies undergo in dense environments. Subsets of our numerical experiments are available upon request.
