Galaxy mergers can rapidly shut down star formation [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2022
Galaxy mergers trigger both star formation and accretion onto the central supermassive black hole. As a result of subsequent energetic feedback processes, it has long been proposed that star formation may be promptly extinguished in galaxy merger ...

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.

Black Holes in Galaxy Mergers

2006
Here we report on simulations which, for the first time, simultaneously track star formation and black hole growth, and associated feedback processes, during collisions of galaxies. We show that encounters and mergers of galaxies lead to strong nuclear gas inflows, fueling both powerful starbursts and rapid growth of central black holes.

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.

Interacting galaxies and mergers

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
