Galaxy Interactions and the Radio Galaxy Phenomenon
1990We have been studying powerful radio galaxies (which we define as having radio power at 178MHz, P 178 ≥ 5xl024 Watts/Hz for a cosmology of H o = 100 km sec-1 Mpc-1 and q o = 0) in order to determine their origins. There are two distinct classes of powerful radio galaxies (PRGs), the so called class A and B radio galaxies (Hine and Longair 1979; Heckman

Dynamics of Interacting Galaxies
Annual Review of Astronomy and Astrophysics, 1992The dynamics of interacting galaxies as observed in the present epoch is reviewed. Topics discussed include numerical methods for modeling galactic interactions, the signatures of interacting galaxies due to tidal forces, and events that add mass to a galaxy.

Interactions and mergers of galaxies
Resonance, 2007When two galaxies approach each other, we can witness the effects of the tidal forces on a gigantic scale. Peculiar features like galactic bridges and galactic tails may form, or the two galaxies may even merge into each other and form a single system. Merger of two spiral galaxies leads to the formation of an elliptical galaxy.

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 ...

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 ...

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
