The Multiplicity Function of groups of galaxies from CRoNaRio catalogues
E. De Filippis, G. Longo, S. Andreon +4
The projected multiplicity function of galaxies gives (per square degree) the density of galaxy aggregates formed by N members. We use the CRoNaRio matched catalogues to derive the…

An automatic procedure to extract galaxy clusters from CRoNaRio catalogs
E. Puddu, S. Andreon, G. Longo +6
We present preliminary results of a simple peak finding algorithm applied to catalogues of galaxies, extracted from the Second Palomar Sky Survey in the framework of the CRoNaRio p…
