Trio of interacting galaxies in the constellation Lynx
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]
