Abstract:Context. The study of the properties of galaxy clusters and their environment gives us information about the formation and evolution of galaxies, groups and clusters, and larger structures -superclusters of galaxies and the whole cosmic web. Aims. We study the relations between the multimodality of galaxy clusters drawn from the SDSS DR8 and the environment where they reside. As cluster environment we consider the global luminosity density field, supercluster membership, and supercluster morphology. Methods. W… Show more
“…These values indicate a rather high quality of the estimation for models with interaction radius smaller than 3 h −1 Mpc. This may be explained by the fact that maybe a change of the clustering regime appears at these interaction ranges [3]. Such a change is also suggested in Figure 6 where the interaction parameter behaves like reaching a maximum around 3 h −1 Mpc.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
