Bar Formation by Galaxy-Galaxy Interactions
2004Bar formation process in interacting galaxies is reviewed on the basis of recent numerical simulations. I focus especially on the possible kinematical difference between tidally-induced bars and spontaneous bars: the former spans a wider range in the rotation rate, depending upon the parameters of the interaction as well as the internal structure of ...

The Hydrodynamical Interaction of Galaxies
1991We present 3D hydrodynamical calculations on interacting/merging galaxies. We find that nearly head-on collisions of galaxies lead to new galaxy formation.

Interacting galaxies and mergers
Astrophysics and Space Science, 1993A study of the merger time-scales of various types of interacting galaxies is conducted on the basis of the collisional theory. The results indicate that in the absence of halos, violently interacting galaxies merge in a time-scale of ~ 108 years; but the mildly interacting ones have merger time-scales from ~ 109 to 1010 years. However, in the presence

1995
Gravitational interactions between galaxies are far more common than one might think, assuming that the space density of galaxies is uniform. The galaxies in effect group themselves in clusters, small groups, or pairs: far from being isolated systems they are formed and evolve in interaction with their environment and in particular with neighbouring ...
