Motion properties of satellites around external spiral galaxies
M. Azzaro, F. Prada, C. M. Gutiérrez
We are analyzing a sample of closeby galaxy systems, each comprising a bright isolated spiral and its satellites. We find an excess (56%) of prograde satellites over retrograde, wh…
Supernovae in Galaxy Clusters
A. Gal-Yam, D. Maoz, K. Sharon +3
We present the results of several surveys for supernovae (SNe) in galaxy clusters. SNe discovered in deep, archival HST images were used to measure the cluster SN Ia rate to z=1. A…
The visible environment of gas-accreting galaxies
D. Bettoni, G. Galletta, F. Prada
We studied the environment of a sample of galaxies in which the presence of polar rings or the presence of gas- and stars- counterrotation is observed. These galaxies are believed…
Structural properties of spherical galaxies obeying the Sersic R^1/n law: a semi-analytical approach
E. Simonneau, F. Prada
By considering that the distribution of measured light along any galactocentric radius of an elliptical galaxy can be well represented by a R^{1/n} Sersic law, we propose in this p…
