UGC 4653
Trio of interacting galaxies in the constellation Lynx
From Wikipedia, the free encyclopedia
UGC 4653 known as Arp 195, is a trio of interacting galaxies located 763 million light-years away from the Solar System in the Lynx constellation.[1] The galaxies are being distorted through gravitational interactions with each other.[2][3] The first known reference for this object, was in 1959 where B.A. Vorontsov-Vel'yaminov compiled it inside the Vorontsov-Vel'yaminov Interacting galaxies, as VV 243.[4]

This image of UGC 4653 was captured by the Hubble Space Telescope.[2] The galaxies make up the 195th object in the Atlas of Peculiar Galaxies created by Halton Arp.[5] They fall into the category of galaxies with material ejected from nuclei.[6]
UGC 4653 has active nuclear regions which produce infrared (IR) emissions.[7] These appear to be more like AGNs than HII regions.[7]
A study published in 2023, confirmed all three galaxies of the UGC 4653 system are spirals. The southern galaxy is a face-on galaxy hosting a bright core, while the central is edge-on but no clear distinction whether it is an early or late-type galaxy. The northern galaxy has a tidal tail and is of late-type morphology. With the exception of the third, both galaxies contain presence of strong emission lines.[8]
Supernova
Type Ia supernova, SN 2008bv[9] was discovered in UGC 4653 with a magnitude of 18.3.[10] It was located 1".7 east and 3".9 south of the nucleus.[11]
