[8] Due to its disturbed appearance, it is object 160 in Halton Arp's 1966 Atlas of Peculiar Galaxies.

This galaxy consists of a brighter central region spanning an angular size 9″ across, with an accompanying system of loops and arcs.

[9] There is a tidal tail and regions undergoing high levels of star formation, making this a starburst galaxy.

[13] Within 1.2 kpc (3.9 kly) of the dynamic center of NGC 4194, star formation is occurring at a rate of 8 M☉·yr−1.

[14] As of 2014, no galactic nucleus has been detected based on radio emissions, nor have the respective nuclei of the merger galaxies.
