Dark matter self-interactions via collisionless shocks in cluster mergers

Physics Letters B, 2015
While dark matter self-interactions may solve several problems with structure formation, so far only the effects of two-body scatterings of dark matter particles have been considered.

A Fast Radio Burst in a Compact Galaxy Group at z ∼ 1

The Astrophysical Journal Letters
FRB 20220610A is a high-redshift fast radio burst (FRB) that has not been observed to repeat. Here, we present rest-frame UV and optical Hubble Space Telescope observations of the field of FRB 20220610A. The imaging reveals seven extended sources, one of

Radio Diagnostics Of Galaxy Interactions [PDF]

Symposium - International Astronomical Union, 1999
The Hickson Compact Groups (Hickson 1982) are relatively isolated systems of galaxies with projected separations comparable to the diameters of the galaxies themselves and are an ideal laboratory for the study of the effects of interactions on the various properties of galaxies.

The Complex Multiwavelength Morphology of the Peculiar Compact Galaxy Group IC 2431

The Astrophysical Journal
We present new Chandra X-ray imaging spectroscopy of the compact galaxy group IC 2431, and compare with archival ultraviolet, optical, infrared, and radio images. IC 2431 is a starburst system containing three tidally distorted disk galaxies.

The Mechanism and Timescale of Nodal Precession: Two Nuclear Stellar Disks in the Galactic Center

Open Astronomy, 2015
A dynamical model of interacting nuclear stellar rings in the central parsec of our Galaxy is constructed. We discuss the physical sources of nodal precession and of the associated time scales.

Interacting galaxies in the NGC 697 group of galaxies [PDF]

Proceedings of the International Astronomical Union, 2016
AbstractWe studied the morphology of two brightest members of the nearby NGC 697 group of galaxies, and found evidence of satellite accretion onto the primary galaxy NGC 697 of the group as well as outer and inner irregularities of the only early-type galaxy NGC 680 of the group, which are probably shaped by recent dry merging event(s).
