SDSSCGB 10189 is a trio of interacting galaxies that is located in the constellation of Boötes.[1] They are located 1.04 billion light-years away from the solar system[2] and are gravitationally interacting.[3]
Characteristics[edit]
The three galaxies involved in the interaction, are PGC 84569 or known as SBS 1520+503 and IRAS 15205+5021,[4] 2MASX J15220246+5010185 or PGC 3845255[5] and SDSS J152202.25+501027.9 or PGC 4530597.[6] All of them have distorted appearances with strands of dust and gas running between them.[7] It is also likely that their interactions cause periods of extreme star formation thus making it into an luminous infrared galaxy.[8] SDSSCGB 10189 is set on a collision course, in which the result will be a single larger galaxy.[7]
This trio is an exceptionally rare combination in the close proximity of each of the galaxies to one another: they are lying only 50,000 light-years apart from one another to the point they are considered close galactic neighbors.[7] To the left of the interacting trio, a foreground dimmer spiral galaxy called PGC 2365567[9] is located which appears to float serenely along the collision.[7]
This observation was conducted to help astronomers understand the origin of massive galaxies. They are called brightest cluster galaxies and suspected they can be formed through merging of large gas-rich galaxies.[7] By looking at SDSSCGB 10189, it shows how galaxies undergo changes through merging and transform over time from disk galaxies to spheroids.[10][11]
