Astrophysical tests of dark matter self-interactions
Reviews of Modern Physics, 2022Self-interacting dark matter (SIDM) arises generically in scenarios for physics beyond the Standard Model that have dark sectors with light mediators or strong dynamics.

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.

Gravitational interactions between galaxies
Physics Reports, 1982Abstract The dynamics of an encounter between two galaxies is discussed. Generally in galactic encounter, on account of the tidal forces, the binding energies of the galaxies increase and hence their relative orbital energy decreases. The former has disruptive effects on galaxies and the latter may lead to the merging of galaxies under certain ...

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 ...

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

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 ...
