Interacting galaxies and mergers

Nature Astronomy, 2019
Two landmark papers in the 1970s contributed strongly to establishing the importance of galaxy interactions and mergers in the formation and evolution of galaxies, using only gravity, and the ensuing dynamical friction.

Interactions and mergers of galaxies

Resonance, 2007
When 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.

Dynamics of Interacting Galaxies

Annual Review of Astronomy and Astrophysics, 1992
The 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.

Galaxy Interactions and the Radio Galaxy Phenomenon

1990
We 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

Interacting galaxies and mergers [PDF]

Astrophysics and Space Science, 1993
A 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
