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…
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…
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…
Redshifts in the Southern Abell Redshift Survey Clusters. I. The Data
M. J. Way, H. Quintana, L. Infante +2
The Southern Abell Redshift Survey contains 39 clusters of galaxies with redshifts in the range 0.0 < z < 0.31 and a median redshift depth of z = 0.0845. SARS covers the region 0 <…
2dFGRS and SDSS Galaxy Group Density Profiles
Eugenia Diaz, Ariel Zandivarez, Manuel Merchan +1
We have analysed the distribution of galaxies in groups identified in the largest redshift surveys at the present: the final release of the 2dF Galaxy Redshift Survey and the first…
