Sites for Gamma-ray Astronomy in Argentina
A. C. Rovero, G. E. Romero, I. Allekotte +9
We have searched for possible sites in Argentina for the installation of large air Cherenkov telescope arrays and water Cherenkov systems. At present seven candidates are identifie…
Fossil Groups in the Millennium Simulation. Evolution of the Brightest Galaxies
Eugenia Diaz-Gimenez, Hernan Muriel, Claudia Mendes de Oliveira
We create a catalogue of simulated fossil groups and study their properties, in particular the merging histories of their first-ranked galaxies. We compare the simulated fossil gro…
Groups of galaxies: relationship between environment and galaxy properties
Hector J. Martinez, Hernan Muriel
We analyse how the properties of galaxies in groups identified in the Sloan Digital Sky Survey depend on the environment. In particular, we study the relationship between galaxy pr…
Photometric observations of Southern Abell Cluster Redshifts Survey Clusters: Structure of galaxies in the inner region of clusters of galaxies
V. Coenda, H. Muriel, C. J. Donzelli +3
We analyze photometric properties of 1384 cluster galaxies as a function of the normalized distance to cluster center. These galaxies were selected in the central region ($r/r_{200…
Structure and dynamics of the Shapley Supercluster
Dominique Proust, Hernan Quintana, Eleazar R Carrasco +8
We present results of our wide-field redshift survey of galaxies in a 285 square degree region of the Shapley Supercluster (SSC), based on a set of 10529 velocity measurements (inc…
Systems of Galaxies in the SDSS: the fundamental plane
Eugenia Diaz, Hernan Muriel
We analyse a subsample of the galaxy groups obtained by Merchán & Zandivarez (2005) from the SDSS DR3 to study the fundamental plane and the mass to light ratio of galaxy groups. W…
