TL;DR
This paper presents GALEX ultraviolet images of interacting galaxy pairs, highlighting tidal features and star formation regions, and identifies a potential 'Taffy' galaxy resulting from a head-on collision.
Contribution
It provides a new UV imaging survey of interacting galaxies, revealing detailed tidal features and star formation not easily seen at other wavelengths.
Findings
Tidal features are prominent in UV images.
Numerous star formation knots are observed in disks, tails, and bridges.
A possible 'Taffy' galaxy resulting from a head-on collision is identified.
Abstract
We present GALEX ultraviolet images from a survey of strongly interacting galaxy pairs, and compare with images at other wavelengths. The tidal features are particularly striking in the UV images. Numerous knots of star formation are visible throughout the disks and the tails and bridges. We also identify a possible `Taffy' galaxy in our sample, which may have been produced by a head-on collision between two disk galaxies.
