Cluster mass estimation through Fair Galaxies
Guido Cupani, Marino Mezzetti, Fabio Mardirossian
We analyse a catalogue of simulated clusters within the theoretical framework of the Spherical Collapse Model (SCM), and demonstrate that the relation between the infall velocity o…
Mass estimation in the outer non-equilibrium region of galaxy clusters
Guido Cupani, Marino Mezzetti, Fabio Mardirossian
We discuss a new criterion to estimate the mass in the outer, non-equilibrium region of galaxy clusters, where the galaxy dynamics is dominated by an overall infall motion towards…
Galaxies in group and field environments: a comparison of optical-NIR luminosities and colors
M. Girardi, F. Mardirossian, C. Marinoni +2
We compare properties of galaxies in loose groups with those in field environment by analyzing the Nearby Optical Galaxy (NOG) catalog of galaxy systems. We consider as group galax…
Morphology and luminosity segregation of galaxies in nearby loose groups
M. Girardi, E. Rigoni, F. Mardirossian +1
We study morphology and luminosity segregation of galaxies in loose groups. We analyze the two catalogs of groups which have been identified in the Nearby Optical Galaxy (NOG) samp…
Optical Luminosities and Mass--to--Light Ratios of Nearby Galaxy Clusters
M. Girardi, S. Borgani, G. Giuricin +3
We analyze a sample of 105 clusters having virial mass homogeneously estimated and for which galaxy magnitudes are available with a well defined high degree of completeness. In par…
The Observational Mass Function of Nearby Galaxy Clusters
M. Girardi, S. Borgani, G. Giuricin +3
We present a new determination of the mass function of galaxy clusters, based on optical virial mass estimates for a large sample of 152 nearby (z\le0.15) Abell-ACO clusters, as pr…
