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.

Interacting galaxies and mergers [PDF]

open access: possibleAstrophysics 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

Transformation of Galaxies by Mergers

2003
The variation of the structural and astrophysical properties of spiral galaxies through the Hubble classification is generally interpreted in terms of an evolutionary sequence. However, the physical mechanisms that could drive this evolution are not fully understood.
