On the relative orientation of binary galaxies

Astrophysics 2007-05-23 v1

Abstract

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 shorter merger times for galaxies with paralel spins. We show by means of N-body simulations that this suggestion is correct.
