On the relative orientation of binary galaxies
Ivanio Puerari, Carlos Garcia-Gomez, Antonio Garijo
The projected directions of the rotation axes of interacting binary disk galaxies tend to align orthogonal to each other. Sofue (1992) has suggested that this could be due to short…

The formation of cD galaxies
A. Garijo, E. Athanassoula, C. Garcia-Gomez
We present N-body simulations of groups of galaxies with a number of very different initial conditions. These include spherical isotropic, nonspherical anisotropic collapses and vi…

Dynamical Evolution of Galaxy Groups. A comparison of two approaches
C. Garcia-Gomez, E. Athanassoula, A. Garijo
In this paper we test the performance of explicit simulations of groups of galaxies, (i.e. simulations in which each galaxy is treated as a mass point and the physics of the intera…
